Question

cone and hemisphere have equal area and bases find ratio of heights ​

Answer 1

Step-by-step explanation:

Area of cone: πr(r+h).

Area of hemisphere: 2πr(r+h)

Area of hemisphere = Area of cone

2πr(r+h)=πr(r+h)

then ratio,

A: hemisphere/A: cone=2πr(r+h)/πr(r+h)

by canceling u get

2h/1h=2h:1h
