Circumference = 16pi ie 2pi*r = 16pi so that r = 8 units Then area = pi*r2 = 64*pi square units.
You need to work backwards. the formula for area is r^2pi=A. to find the radius, r, you divide the diameter in half. therefore (d/2)^2pi=Area. plug in your #'s an solve. Ex. Area=16pi Find diameter. (d/2)^2pi=16pi divide both sides by pi (d/2)^2= 16 take the square root of both sides d/2=4 multiply both sides by 2 d=8
C=2Pir, since r is 8. the answer would be 16pi.
16pi. If your talking feet would be approximately 50 feet
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

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

suppose circumference= X X/pi = diameter X/2pi = radius and you square it to get X^2/(16pi) Times pi to get (X^2)/16
The circle has an area of 16pi m2 or approximately 48m2.
The area of a circle that has a circumference of 16pi is: 201.1 units2
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 surface area of the top of the cylinder is pi(r)2. In this case r = 4 inches, so the surface area of the top is 16pi. The surface area of the bottom is also 16pi. The surface area remaining is equal to the height of the cylinder (in this case 5 inches) multiplied by the circumference of the top (in this case 2 * pi * 4 = 8pi). So the surface area of the remaining side is 5 * 8pi = 40pi.40pi + 16pi + 16pi = 72pi cubic inches. That is approximately 226.19 in3.
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
