To find the radius of a circle with a circumference of 30 cm, we can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given C = 30 cm, we can plug this value into the formula and solve for r.
30 = 2πr r = 30 / (2π) r ≈ 4.77 cm
Therefore, the radius of the circle is approximately 4.77 cm.

If the radius of the circle above is 30 mm. What is the circumference of the circle (Use 3.14.)?
188.40 mm
If the circumference of a circle is 30 what is its radius?
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
If the radius of a circle is tripled what happens to the circumference?
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.
What is the circumference of a 30 foot circle?
The circumference of a 30-foot diameter circle is: 94.248 feet.
If the circumference of a circle is 30 cm what is the diameter?
If the circumference of a circle is 30 cm its diameter is: 9.549 cm
