Question

Find the perimeter of the window to the nearest hundredth

Answer 1

The Perimeter of the window to the nearest hundredth is 4.71 ft

The Perimeter of a semi circle is a measure of its circumference. The formula for the circumference of the semi-circle is :

• Circumference = πr
• r = radius = 3/2 = 1.5 ft

Inputting our values into the formula ;

Circumference = 3.14 × 1.5 = 4.71 ft

The Perimeter of the window is 4.71 ft

Answer 2

9.43ft

Explanation:

Given

`d = 3ft`

Required

Determine the perimeter

To do this, we simply calculate the circumference;

This gives:

`C = \pi d`

`C = (22)/(7) *3`

`C = (66)/(7)`

`C = 9.43ft`
