i need help please!!

Answer:
39.27
Step-by-step 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
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.
