Step-by-step explanation:
Given From a solid wooden sphere with 13 centimetres radius, a cone with 18 centimetres height and maximum base is made.
- b. OR = OQ = 12
- OS = 18 – OR
- = 18 – 13
- = 5
- So r = QS = 12 cm
- so radius of cone is 12 cm
- c. We know that volume of cone = 1/3 π r^2 h
- = 1/3 x 22/7 x 144 x 18
- = 57,024 / 21
= 2715.42 cm^3
