estimate the radius of a circle with circumference of 272.2 inches use 3.14 for pi round to the nearest tenth
A. 43.3
B.136.1
C.86.7
D.5887.2
the answer is A bc you are looking for the radius which is half of the circle the diameter is C
What is your answer?
I showed you how to do this, but you haven't posted your answer.
90
than was the answer but not the one that i am looking for
Since it asked for an estimate and
and Dπ = C
I would approximate
270/3 = 90
so the diameter is about 90, making the radius about 45
Since they wanted an estimated answer, giving answers with those kind of decimals makes no sense. Using 3.14 for π is not estimating.
