c=65.94ft

r=?

c = circumference??

r = radius??

Circumference of a circle=2x3.142xr

Since the c is 65.94
That is 65.94=2x3.142xr
65.94/6.2831853=r
R=10.49467695 approximately 10.5
(N:B 6.28... Was found by 2 x 3.142)

To find the radius (r) of a circle, you can use the formula for the circumference of a circle, which is given by:

C = 2πr

Given that the circumference (C) is 65.94 feet, we can rearrange the formula to solve for the radius.

Start by dividing both sides of the equation by 2π:

C/(2π) = r

Now we can substitute the given value of C into the equation:

65.94/(2π) = r

To find the radius, you would need to calculate the value of this expression using a calculator:

r ≈ 10.50 feet (rounded to two decimal places).
