Question

What is the total area of this composite figure rounded to the nearest hundredth?

18.53 ft2
43.07 ft2
39.53 ft2
20.07 ft2

Answer 1

39.53 ft^2

Explanation:

We can find the area of the rectangle

A = l*w

= 12*3 = 36

And the area of the semicircle

A = 1/2 pir^2

The diameter is 3, the radius is 3/2

=1/2 pi* (3/2)^2

= 1/2 *3.14 * 9/4

3.5325

Add the two areas together

36+3.532539.5325

Rounding to the nearest hundredth

39.53 ft^2
