Q:
# This figure consists of a rectangle and a quarter circle.What is the perimeter of this figure?Use 3.14 for π .

Accepted Solution

A:

Hello!

First you have to find the length of the side under the quarter circle

20 - 11 = 9

------------------------------------------------------------------------------------------------------

Next you have to find the circumference of the quarter circle

You use the equation to find the circumference of a circle and divide the answer by 4

The equation is [tex]2 \pi r[/tex]

r is radius

Put in 3.14 for pi and the numbers you know

2 * 3.14 * 11 = 69.08

Divide this by 4

69.08 / 4 = 17.27

-----------------------------------------------------------------------------------------------------

Finally you add all the values you know

20 + 2 + 17.27 + 9 + 11 + 2 = 61.27cm

------------------------------------------------------------------------------------------------------

The answer is 61.27cm

Hope this helps!
