Question

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

Answer 1

Well if it's circumference is 272.2, the radius would be 136.1, would it not? 272.2 / 2 gives that answer.

Answer 2

I have longest name.

. . .

Answer 3

you need to use the equation C=2(pi)r to solve the question. C=272.2, pi=3.14, r then equals 272.2/3.14/2=43.34, So A is the correct answer.

Answer 4

Ah wait, lemme redo this. I got circumference mixed up with diameter.

Answer 5

i think your right

Answer 6
