Question

Find the perimeter of this semi-circle with diameter,

d
= 34cm.
Give your answer as an expression in terms of
π
.

Answer 1

The answer to your question is P = 17(π + 2) or 17π + 34

Explanation:

Data

Diameter = 34 cm

Formula

P = rπ + 2r

Process

1.- Find the radius

radius = diameter / 2

radius = 34 / 2

radius = 17 cm

2.- Substitute the values in the formula

P = 17π + 2(17)

3.- Simplification

P = 17π + 34

4.- Factor

P = 17(π + 2)
