Answer: 65.94 m^3

Step-by-step explanation:

The volume of a cone is [tex]\pi * r^2*h/3[/tex]

[tex]\pi = (3.14) || r^2 = (3^2)||h/3 = (7/3)[/tex]

Step 1. Simplify the expression.  [tex]3.14 * 9*7/3[/tex]

Step 2. Multiply 9 * 3.14. [tex]28.26 * 7/3[/tex]

Step 3. Finish simplifying. [tex]28.26 * 7/3 = 65.94[/tex]

Answer:

50 is not a triangular number

Step-by-step explanation:

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 =55

The way to calculate triangle numbers is to add the corresponding number.

For example, 1 is a triangle 1 + 2 is a triangle 1 + 2 + 3 is a triangle so on and so forth.

Triangle numbers would be 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, and 91

Answer:Therefore, the percent change from 56 to 77 students is 37.5%.

Step-by-step explanation:

students, we can use the following formula:

percent change = ((new number - old number) / old number) x 100%

Plugging in the values given in the problem, we get:

percent change = ((77 - 56) / 56) x 100%

percent change = (21 / 56) x 100%

percent change = 0.375 x 100%

percent change = 37.5%

Therefore, the percent change from 56 to 77 students is 37.5%.

Answer: 37.5%

Answer:

153 units squared

Step-by-step explanation:

first, multiply 10 x9 to find the area of the rectangle, which is 90

then find the area of the triangle. The formula for area of a triangle is

A=1/2bh

so, 7 x 9= 63 divided by 2 is 31.5

since there are 2, multiply 31.5 x 2= 63

add 63 to 90 which is 153

Answer: 153 sq. units

Step-by-step explanation:

Base a = 10

Base b  = 7x2 = 24

Height = 9

area of trapezoid = 1/2 * (a+b) * h

= 10+24 * 9 /2

= 306/2 = 153

Answer:

Step-by-step explanation:

The total cost of the nickel for the sculpture is $12,660.48.

We know that the volume of a cone is:

v = 1/3πr²h  ......(i)

where r ⇒ radius of the cone

h ⇒ height of the cone

Now, as per the question,

r = diameter/2 = 16÷2 = 8 inches

h = 84 inches

Putting the values in equation (i)

v = 1/3 × 3.14 × (8)² × 84

v = 5626.88 cubic inch

The cost given for nickel = $2.25 per cubic inch

So, the total cost for the nickel used in making the sculpture:

the volume of cone × cost per cubic inch

5626.88 × 2.25 = $12,660.48

Therefore, the total cost for the nickel used is $12,660.48

-m+15/6

2/3m-5/3m-5/2

Answer: 1 5/6m - 2 1/2

Step-by-step explanation:

(2/3m - 1 1/6) + (5/6m - 1 1/3)

2/3m X 2 = 4/6m

4/6m + 5/6m = 11/6m=1 5/6m

-1 1/3 X 2 = -1 2/6

-1 2/6 - 1 1/6 = -2 1/2
