What is the best approximation for the perimeter of a semicircle with a diameter of 64 meters?

use 3.14 to approximate pi.

a. 100.48 m

b.164.48 m

c. 200.96 m

d. 264.96 m
i think it's b, can someone check my answer?

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024
