Question

A company makes similar cylindrical containers in two sizes, as shown in the table below.

Containers Radius(in Cm) Volume(in Cubic Cm)
Type 1 4 ??
Type 2 7 1231.66

What is the volume, in cubic centimeters, of Type 1 containers?

Answer 1

v cylinder = pi * r2 * h

so for type 2 = 1231.66 = pi * r2 * h
therefore h = (1231.66 )/ (pi * r2)

FOr Type 1 = V = pi * 4 sq * 1231.66 / (pi * 7 sq)

So V = 402.174 cm cube..
