Henry knows that the circumference of a circle is 18(3.14) inches. What is the area of the circle?

Henry knows that the circumference of a circle is 18(3.14) inches. Circumference = Pi x d = 3.14 x d = 18(3.14) d = 18 inches, r = d/2 = 9 inches. Circle area = 3.14 x 9^2 = 254.34 squre inches.

Henry knows that the circumference of a circle is 18(3.14) inches.

Circumference = Pi x d = 3.14 x d = 18(3.14)

d = 18 inches, r = d/2 = 9 inches.

Circle area = 3.14 x 9^2 = 254.34 squre inches.

Circumference = Pi x d = 3.14 x d = 18(3.14)

d = 18 inches, r = d/2 = 9 inches.

Circle area = 3.14 x 9^2 = 254.34 squre inches.
