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.
The radius if the circle is half of its diameter and so 30/2 = 15 mm
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.
