Question

I need help please!!

Answer 1

39.27

Explanation:

Calculate whole area of circle - pi5^2 = 78.54

Divide answer by 2 as only half of the circle is shaded - 78.54/2 = 39.27

Answer 2

To solve for the area, you cannot solve for just half, so you first have to solve the whole entire area. A = πr².

π5² = 78.5

So, 78.5 is the answer to the circle area.

But half the circle is dividing the whole area by half.

78.5/2=39.25

So 39.25m² is the answer.
