Question

The circumference of a circle is 36 x feet. What is the length of the radius of this circle?

Answer 1

Answer: 5.73 ft

Explanation:

The formula for the circumference of a circle is C=2(pi)r.

We know what the circumference is, so we can plug it into the formula ti get: 36=2(pi)r.

Now, we solve for the radius (r).

Divide 36 by 2(pi).

Then you get r=5.73 ft

Answer 2

5.732484076 =r

Explanation:

The circumference is 36 ft

We know the circumference is given by

C = 2 * pi *r

36 = 2 * pi *r

Divide each side by 2 pi

36/ 2pi = 2 *pi*r/2*pi

18/pi = r

Letting pi be approximated by 3.14

18/3.14 =r

5.732484076 =r
