What is the area of the circle above? (Use 3.14 for .)

Question

A.
31.4 sq in
B.
78.5 sq in
C.
15.7 sq in
D.
157 sq in

Circle with 5m inside it

Answer 1

To calculate the area of a circle, we use the formula A = πr², where A represents the area and r is the radius of the circle.

Given that the radius of the circle is 5m, we can substitute this value into the formula.

A = π(5m)²
A = π(25m²)
A ≈ 3.14 * 25
A ≈ 78.5 sq m

Therefore, the area of the circle is approximately 78.5 sq m. Thus, the correct answer is B. 78.5 sq in.
