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

Answer:

$A=\dfrac{3.14r^2}{2}$

Step-by-step 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,

$A=\dfrac{\pi r^2}{2}\\\\or\\\\A=\dfrac{3.14r^2}{2}$

Hence, this is the required solution.
