Divide the area by Pi to get the diameter.
diameter = 15pi/pi = 15 units in length
Circumference = Pi multiplied by the diameter. C = (3.1415)(15 in.) = 47.12 in. Therefore, the circumference of a circle with a diameter of 15 in. and a radius of 7.5 in. is approximately 47.12 inches.

Divide the area by Pi to get the diameter.
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
The diameter of a circle with a circumference of 15 centimeters is about 4.775 cm
It is 238.073 metres, or approx 781 feet.
Well, honey, the radius of a circle is always half of the diameter. So if the diameter is 30 mm, the radius would be 15 mm. It's basic math, darling. Hope that clears things up for you!
The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
1 acre = 43,560 square feet 80 acres = 3,484,800 square feet area of a circle = (pi)radius squared 3,484,800 divided by pi = radius squared square root of 1,109,244 = radius 2 times 1053.2 = 2106.4 feet is the approximate diameter of an 80 acre circle of land
diameter is 15 area of the circle is... 706.5 if im not mistaken
diameter = 15pi/pi = 15 units in length
7.5Radius of circle: 15/2 = 7.5 cm
Radius is half of the diameter
The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 cm.
