Hello!
The formula for circumference of a circle is:
C = 2 × 3.14 × r
We will find the circumference if the circle in the picture using this formula. Since we already have the radius of the circle (25 m) finding the circumference will be easier.
Substitute:
C = 2 × 3.14 × 25
C = 6.28 × 25
C = 157
A N S W E R:
The circumference of the circle is D. 157 m.
*Make sure you always use this formula when finding the circumference! :D
