The perimeter is composed of two straight parts and two semicircles. We can use this to break down the problem.

We can find the straight parts easily. They are given in the problem.

straight parts: 82 x 2 = 164 m

The two semicircles make a circle. We just have to find the circumference of a circle with a diameter of 66 cm to get the length of the semicircles.

semicircles: 2(π)(66/2) = 66(3.14) = 207.24 m

answer: 164+207.24 = 371.24 m

How do you do this?please help

d1i1m1o1n [39]

Answer:

10.5 ft.

Step-by-step explanation:

1. Find the radius of the larger circle

4/7 = 3/r --> the ratio should be constant

cross-multiplication: 21 = 4r

Divide: r = 5.25 ft.

2. Find the circumference

Equation: C = 2πr

C = 2π*5.25

C = 10.5π ft.
