Question

The radius of the circle above is 32 mm. What is the circumference of the circle? (Use = 3.14.)

Answer 1

200.96

Explanation:

The circumference of a circle can be found using:

c=2*pi*r

We know that the radius is 32 millimeters. We also know we are using 3.14 for pi. So, we can substitute 32 in for r and 3.14 in for pi.

c=2*3.14*32

Multiply all the numbers together

c=64*3.14

c=200.96

The circumference is 200.96 mm.

Answer 2

200.96mm or 20.096cm

Explanation:

The formula for circumference of a circle is C=2pi*r

r is the radius, pi is equal to 3.14. Input into the equation and you get the answer 200.96mm.
