Question

Using a tape measure, Melanie found that the circumference of the great

redwood was 600 cm. She estimated that its diameter was 200 cm. Was
Melanie’s estimate a little too large, a little too small or right on?

A little too large
Right on
A little too small

Answer 1

Explanation:

A. Little too large

Because

C= (Pi)*d

600=(pi)*200

So the answer is the A.

Answer 2

Circumference is pi x diameter so we have to divide 600 by pi to get the actual diameter. 600÷3.14=191cm, so her estimate was a little too small
