Question

Question 14
Find the perimeter.

Answer 1

A

Step-by-step explanation: 6 5 17 17

the perimeter is a semi-circle PLUS the diameter d = 6 ft

so

C = 2π r semi-circle C/2 = π r r = d/2 = 3 ft

total perimeter is

perimeter = C/2 + d

= π r + d

= 3π + 6

= 3(3.14) + 6

= 15.425 ft

Answer 2

below

Explanation:

perimeter of a semicircle

½*2πr

=πr

=3.142*3

=9.42 ft
