Question

14

Find the area of the semicircle.
Either enter an exact answer in terms of 7 or use 3.14 for it and enter your answer as a decimal.

Answer 1

76.93

Explanation:

Answer 2

The area of the semi-circle = 76.93 square units

Explanation:

Explanation:-

Given that the diameter of the circle d= 14

We know that Area of the circle

A = πr²

The radius of the circle

`r = (d)/(2) = (14)/(2) = 7`

The area of the semi-circle

`A = (\pi r^(2) )/(2)`

`A = (\pi (7)^(2) )/(2) = (49\pi )/(2)`

Put π = 3.14

The area of the semi-circle

`A = (3.14 X 49)/(2) = 76.93 square units`
