Q:

A window has the shape of a rectangle with a semicircle at the top Find the approximate area of the window using the dimensions shownA about 9.57B about 14.28C about 11.14D about 20.56

Accepted Solution

A:
To solve this problem you must apply the proccedure shown below:

 1. You need to apply the formula for calculate the area of a rectangle and the formula for calculate the area of a semicircle, which are:

 - Area of the rectangle:

 A1=bh

 Where b is the base and h is the height

 A1=(4 ft)(2ft)
 A1=8 ft²

 - Area of the semicircle:

 A2=πr²/2

 Where r is the radius.

 A2=π(1 ft)²/2
 A2=1.57 ft²

 2. Therefore, the area of the figure is:

 At=A1+A2
 At=9.57 ft²

 The answer is the:

 A. About 9.57
