Question

How do you find the diameter of a circle that has circumference of 81 meters?

Answer 1

By using the formula

C = pi*d

where

C = circumference of circle
pi = 3.14 (approximately)
d = diameter of circle

Answer 2

I don't think I did it right. I got 25,434. What did you get?

Answer 3

C = pi*d

81 = pi*d ... plug in the given circumference, solve for d

81/pi = d

d = 81/pi

d = 81/3.14

d = 25.796178343949

That's approximate of course. Use more decimal digits of pi to get a more accurate answer.

Answer 4

ok.

Answer 5

not sure how you got 25,434

Answer 6

maybe you multiplied?
