Question

A solid metallic hemisphere of radius 8cm is melted andrecastedinto a right circularconeof base radius 6 cm. Determine the height of the cone.
${use = \pi = 22 \frac{7}$
​

Answer 1

Answer:

• vol of sphere = 4πr^2h/3
• vol of cone =πr^2/3
• vol of sphere= vol of cone
• 4×8×8×8×π/3= π6×6h/3
• 512/9= h
• 56.88cm=h
