What’s the radius?

Question

a.Find the radius of a circle with a circumference of 0.94 m

b.find the radius of a circle with a circumference of 92 cm

Answer 1

a) The formula for circumference of a circle is:

C = 2 * π * r,

where C = circumference and r = radius. We can rearrange that to get:

r = C / (2 * π)

Then, substituting 0.94 m for C, we get 0.94 / (2π), or about 0.1496 m

b) Using the same formula, we can get 92 / (2π), or about 14.642 m
