Best Answer

area = {pi}r2

= 16{pi}

--> r2 = 16

--> r = 4

circumference = 2{pi}r

= 2{pi}4

= 8{pi}

You dived the area by the circumference of the circle.

Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).

Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)

The area of a circle with circumference 9.42in is: about 7.061 square inches.

The area of a circle with a 12-foot circumference is about 11.46 square feet.

If the circumference of a circle is 16pi feet, the area is: about 201.1 square feet.

The area of a circle that has a circumference of 16pi is: 201.1 units2

Circumference = 16pi ie 2pi*r = 16pi so that r = 8 units Then area = pi*r2 = 64*pi square units.

Circumference of a circle is the diameter times pi or 2pi times the radius. Given the diameter, circumference = 16 times pi. So, the circumference is 16pi or 50.265

The circle has an area of 16pi m2 or approximately 48m2.

16pi. If your talking feet would be approximately 50 feet

use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi

use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi

Circumference is 2piR where R is the radius. Radius is 1/2 diameter so R = 8. Therefore circumference is 2x8xpi which is 16pi or 50.265

The Area of a circle is Pi (r)(r) so the area of a circle with the radius of 4, would be 16pi

The radius is 8 feet.
