A cylinder container of radius 15 cm has some water in it. When a solid submerged into the water, the water level rises 1.2 cm.

Question

(a) Find, the volume of the water displace by the solid leaving your answer in terms of π
(b) If the solid is a circular cone of the height 9 cm, calculate the radius of the cone

Answer 1

v = 225π*1.2

1/3 πr^2 = 9
