Answer:

28.3 square inches

Step-by-step explanation:

Use the area of a circle to determine its area:

[tex]A=\pi r^2\\\\A=\pi(3)^2\\\\A=9\pi\\\\A=9(3.14)\\\\A=28.26\\\\A\approx28.3[/tex]

Therefore, the area of a circle with a radius of 3 inches is 28.3 square inches

Answer:

Area of circle = [tex]\boxed{\sf{28.3 \: {in}^{2}}}[/tex].

Step-by-step explanation:

Here's the required formula to find the area of circle :

[tex]\twoheadrightarrow{\pmb{\sf{A_{(Circle)} = \pi{r}^{2}}}}[/tex]

A = Area π = 3.14 r = radius

Substituting all the given values in the formula to find the area of circle :

[tex]{\twoheadrightarrow{\sf{Area_{(Circle)} = \pi{r}^{2}}}}[/tex]

[tex]{\twoheadrightarrow{\sf{Area_{(Circle)} = 3.14{(3)}^{2}}}}[/tex]

[tex]{\twoheadrightarrow{\sf{Area_{(Circle)} = 3.14{(3 \times 3)}}}}[/tex]

[tex]{\twoheadrightarrow{\sf{Area_{(Circle)} = 3.14{(9)}}}}[/tex]

[tex]{\twoheadrightarrow{\sf{Area_{(Circle)} = 3.14 \times 9}}}[/tex]

[tex]{\twoheadrightarrow{\sf{Area_{(Circle)} = 28.26}}}[/tex]

[tex]{\twoheadrightarrow{\sf{Area_{(Circle)} \approx 28.3}}}[/tex]

[tex]\star{\boxed{\sf{\red{Area_{(Circle)} \approx 28.3 \: {in}^{2}}}}}[/tex]

Hence, the area of circle is 28.3 in².

Answer:6

Step-by-step explanation:

using BIDMAS: Brackets,Indices,division,multiplication,addition,subtraction.

1) Firstly you do the problem in the brackets. (-19 - -20) two negatives next to each other make a plus(+) meaning (-19 - -20) = (-19+20) which = 1

2) Next Step is to do the multiplication section. Since we got 1 in place instead of (-19 - -20) we multiply -3 by 1 which = -3.

3) Now the equation we have is 11 + -8 - -3. In BIDMAS both addition and subtraction are equal therefore we can do it in any order. 11 + -8 is the same as 11 - 8 = 3

4) The problem we have now is 3 - -3, like we said before two negatives next to each other make an addition sign(+) so 3 - -3 = 3+3 = 6, therefore getting the answer 6.

Thank you for reading,please let me notify me if I've missed anything out!

Shannon test-drives a car in Germany and drives 95 kilometer per hour. What is her speed in miles per hour? (1 kilometer < 0.62 mile) step by step

Answers

Answer:

58.9 miles per hour

Step-by-step explanation:

Step 1: Convert 95 Kilometers per hour to miles per hour

1 Kilometer = 0.62 miles

95 Km x [tex]\frac{0.62 miles}{1 km}[/tex]

cancel Km

95 Km x [tex]\frac{0.62 miles}{1 km}[/tex]  = [tex]\frac{95}{1}[/tex] x [tex]\frac{0.62 miles}{1}[/tex] = [tex]\frac{58.9 miles}{1}[/tex] or 58.9 miles

Change it into speed

58.9 miles per hour (59 miles per hour (Round off))

(Note: I don't know if I should round off because the instructions aren't that clear. This solution might or might not have been thought to you by your lecturer.)

Using the triangle below, set up and solve an equation in order to find the value of x.

Answers

180 degrees - 118 degrees - 34,6 degrees = 27, 4 degrees

Since the interior angles of a triangle sum up to 180 degrees.

Hope it helps!✨

Answer:

x = 180 - 118 - 34.6 = 27.4

Step-by-step explanation:

The sum of the internal angles of each type of (2D) polygon will only have 1 specific value for each polygon. In the case of a triangle, the interior angles add up to 180 degrees.

Using a statement-reason approach, we start by saying:

Q^ + R^ + S^ = 180 degrees  (*)                 Interior angles of a triangle = 180

(*Please use proper notation if you were already taught it - these computer keyboards can only do so much you know...)

Then you just solve normally for x:

34.6 + 118 + x = 180

x = 180 - 118 - 34.6

x = 27.4 degrees
