Question

Find the circumference of the circle (use 3.14 for pi). Show your work. Round to the nearest tenth.

Answer 1

\(2\pi r\)?

Answer 2

...except that's the Area and not the Circumference.

Answer 3

Yes, the question wants circumference. C = pi*d, where d is the diameter of the circle.

Answer 4

*facepalm*.. apologies
\[\large C=2\pi r\]given that \(r=25\) (and \(\pi=3.14\)), plug in the values and solve:\[\large C=(3.14)\times(25)\]\[\large C=78.5~sq~units\]
