diameter, how many inches will it roll in
8 revolutions along a smooth surface? A.)121π in. B.)168π in. C.)176π in. D.)228π in.

Respuesta :

You first need to calculate the circumference as that will give you the distance in one revolution.

Then you multiply the answer you get by 8
 
Circumference = pi*diameter = 22pi 8 revolutions = 8*22*pi = 176pi
