Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.

Circumference = pi x diameter so if the radius is 5 then the diameter is 10 Circumference = pi x 10 = 31.415 If we triple the radius to 15, then the diameter is 30, so Circumference = pi x 30 = 94.245 Which looks like triple the first circumference. So if the radius is tripled, the circumference is also tripled.

The circumference of a 30-foot diameter circle is: 94.248 feet.

If the circumference of a circle is 30 cm its diameter is: 9.549 cm

The circumference of a circle is 360 degrees. The circumference of a circle is also 2*pi*radius or diameter*pi.

Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.

360/30*2 = 24 = circumference of the circle 24/2*pi = 3.819718634 inches = radius of the circle

the diameter of a circle that is 60 is 60 radius is 30 the circumference is 188.46

double the radius to get the diameter = 30 multiply by pi (3.1415...) = 92.245 cm
