Question

Mr. Smith built a patio shaped like a semi-circle.

image

Which expression can Mr. Smith use to get closest to the area of his patio?

Answer 1

1/2(πr^2)

(btw ^2 is an exponent and r is radius)
In order to find the area of a semi circle, you would find the area of the circle as normal, then divide it by two, since a semi circle is half a circle. I don’t see any image, so i recommend you plug the radius of the patio into the expression i gave. hope that helps :)
