Q2 of 18 Page 13

The volume of a vessel in the form of a right circular cylinder is 448π cm3 and its height is 7 cm. Find the radius of its base.

Height of a right circular cylinder is 7 cm
Volume of a right circular cylinder is 448π cm3
π r2h = 448π r2 h = 448
7 r2 = 448
r2 = 64
r = 8 cm
Therefore the radius of its base is 8 cm.
