4.krissa drew a circle with a radius of 4 inches. fill in the blanks. the area of the circle is square inches and the circumference is inches. 64π, 16π 16π, 8π 16π, 64π 8π, 16π

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.
