Question

Mr. James has cylindrical beakers that measure 4 inches in diameter and 9 inches high. What is the volume contained within the beakers? Use 3.14 for pi. Round your answer to the nearest hundredth.

Answer 1

So 4 inches diameter result the radius is 4/2 = 2 inches 

area of base = pir^2 = 3,14*2^2 = 3,14*4 = 12,56 inches squared 

volume = area of base *height 

V = 12,56 *9 = 113,04 so rounded 113,05 inches cubed 

hope this will help you
