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:

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
