Question

if a questions asks to find the area of half of the circle would you do 3.14(pie) times r2(radius squared) times 1/2? and if no then what would you do?

Answer 1

`A=(3.14r^2)/(2)`

Explanation:

The area of a circle is given by :

`A=\pi r^2`

Where

r is the radius of the circle.

If we talk about the area of half of the circle, it means we have to half the area such that,

`A=(\pi r^2)/(2)\\\\or\\\\A=(3.14r^2)/(2)`

Hence, this is the required solution.
