Question

4.Krissa drew a circle with a radius of 4 inches.

Answer 1

The answer is Area= 50.265 and the circumference is 25.133

Answer 2

Answer: second option: 16π, 8π

Explanation:

1) To calculate the area use the formula:

Area = π (radius)^2

radius = 4 in => area = π (4 in)^2 = 16π in^2

2) To compute the circumference use the formula:

Circumference = 2π(radius)

=> Circumference = 2π (4 in) = 8π in.
