Question

What is the diameter of a circle that has areaequal to 484T?

Answer 1

Area of a circle = π r^2

Where r is the radius

Since the area given is 484π, replacing:

484π = π r^2

Solve for r

484π / π = r^2

484 = r^2

√484 = r

r = 22

Diameter = 2 *¨radius = 2 * 22 = 44

Diameter = 44 ( C)
