Find the volume of the right circular cone with radius 3.5 cm and height 12 cm.
Answer:
Solution:
Consider a cone with a height of "h" and a circular base with radius "r." This cone's volume will be equal to one-third of the base's area multiplied by its height.
Given radius, r = 3.5 cm
Height, h = 12 cm
Volume of the cone = (1/3)π r2h
=(1/3)×(22/7)×3.52×12
= (22/7)×12.25×4
= 154 cm3
Hence the volume of the cone is 154 cm3.
