Question

Find the area of the semicircle.

Either enter an exact answer in terms of pi or use 3.14 for pi and enter your answer as a decimal. Diameter= 14. PLZ HELP

Answer 1

The unit is unit square or we can also find a by replacing pi by 3.1. 4 point so this equals 2 times of 3.14 and this equals 6.28. This is a unit square, and so the exact area of semicircle is 2 pi unit square or in terms of decimals. It is 6.28 unit square.

Answer 2

A = 49/2 pi

Explanation:

The diameter is 14 and the radius is 1/2 of the diameter

r =14/2 =7

We want to find the area of 1/2 of the circle

A = 1/2 pi r^2

A = 1/2 pi (7)^2

A = 49/2 pi
