What is the surface area of the cylinder with height 6 ft and radius 6 ft? Round your
answer to the nearest thousandth.

Answers

Answer 1

The surface area of this cylinder to the nearest thousandth is equal to 452.448 square feet.

Given the following data:

Height of cylinder = 6 ft.Radius of cylinder = 6 ft.

To calculate the surface area of this cylinder to the nearest thousandth:

How to calculate surface area.

Mathematically, the surface area (SA) of a cylinder is given by this formula:

[tex]SA = 2\pi rh + 2\pi r^2[/tex]

Where:

h is the height.r is the radius.

Substituting the given parameters into the formula, we have;

[tex]SA = 2 \times 3.142 \times 6 \times 6 + 2 \times 3.142 \times 6^2\\\\SA = 226.224 + 226.224[/tex]

SA = 452.448 square feet.

The equation has a solution of x = 5. What is the value of k? k =.

Answers

The value of k is -11.

Given

The equation 3√(x-k)-2=10 has a solution of x = 5.

How to find the value of k?

To find the value of k put x = 5 in the equation then solve for the value of k.

Therefore,

The value of k is;

[tex]\rm 3\sqrt{x-k}-2=10[/tex]

Substitute x = 5 in the equation

[tex]\rm 3\sqrt{5-k}-2=10\\\\\rm 3\sqrt{5-k}=10+2\\\\\rm 3\sqrt{5-k}=12\\\\\rm \sqrt{5-k}=\dfrac{12}{3}\\\\ \sqrt{5-k}=4\\\\[/tex]

Squaring on both sides

[tex]\rm \sqrt{5-k}=\dfrac{12}{3}\\\\5-k=16\\\\-k = 16-5\\\\-k=11\\\\k=-11[/tex]

Hence, the value of k is -11.

the equation is true

Step-by-step explanation:

solve the equation 4x + 6 = 4 + 2(2x + 1). Which choice describes the meaning of his result, 6 = 6?

4x + 6 = 4 + 2(2x + 1)

4x + 6 = 4 + 4x + 2

6 = 4 + 2

A number is greater than 8. The same number is less than 10. The inequalities x greater-than 8 and x less-than 10 represent the situation. Which best explains the number of possible solutions to the inequality? There is one solution because 9 is the only number between 8 and 10. There are a three solutions because 8, 9, and 10 are possible solutions. There are a few solutions because there are some fractions and decimals between 8 and 10. There are infinite solutions because there is always another number between any two numbers.

Answers

Answer:

Our inequality is 8 < x < 10, where x is our number.

Since the problem doesn't specify whether the number x is an integer or not, we can assume that x can be either a decimal or a whole number. That means that we want any decimal number or whole number between 8 and 10. The only whole number is 9, but there are infinitely many decimal solutions. For example, we could have 8.001, 8.0001, 8.00001, etc.

Thus the answer is D.

[tex]\angle F \text{ and } \angle R[/tex]

========================================

Explanation:

The order of the lettering of GFHE and TRQS is important.

This is because the letters of each pair up together

G pairs with T (first letters)F pairs with R (second letters)H pairs with Q (third letters)E pairs with S (fourth letters)

Because the figures are similar, the paired angles are congruent. So we can say [tex]\angle F \cong \angle R[/tex]

In terms of a visual confirmation, angles F and R are located in the bottom left corner. So this helps back up the answer. Though keep in mind that often the diagrams are misleading and not drawn to scale. So we can't always rely solely on the diagram.

Two buses leave a station at the same time and travel in opposite directions. One bus travels 18 mi/h faster than the other. If the two buses are 994 miles apart after 7 hours, what is the rate of each bus

Answers

Answer:

The distance each bus travels is given as d=tr where

- d is distance bus travels

- t is a time bus travels

- r is the speed of the bus

:

Distance first bus travels for 4 hours is d1=4r.

Distance other bus travels for 4 hours is d2=4(r+12).

:

The total distance between them is 480 miles and since they go in opposite directions this distance is the sum of distances each bus travels.

:

d1+d2=480

4r+4(r+12)=480

4r+4r+48=480

8r+48=480

8r=432

r=432/8

r=54 mph, this is a speed of the first bus

:

r+12=66 mph, this is the speed of the second bus

Step-by-step explanation:

Answer:

24

Step-by-step explanation:

The formula for calculating the sum of interior angles is:

(n - 2) x 180°  (where n is the number of sides)

interior angle of a polygon = sum of interior angles ÷ number of sides

165 = [ (n - 2) x 180° ] ÷ n

Mulitply both sides by n:             165n = (n - 2) x 180°

Expand brackets:                         165n = 180n - 360

Add 360 to both sides:    165n + 360 = 180n

Subtract 165n from both sides:   360 = 15n

Divide both sides by 15:                 24 = n

Therefore, the number of sides = 24

Answer:

you need to place the centre of your protractor on the vertex of the two lines.  

Step-by-step explanation:

Once you place it on the vertex, since the horizontal line is on the left side of the protractor, you start measuring the angle from the left side.

You keep on measuring the point where 2nd line overlaps some angle marking on the protractor.

For the bottom left angle, you need to place the protractor diagonally on the right most line as the horizontal line and then measure the angle.
