Question

Abhay got a playing top as his birthday present, which surprisingly had no colour on it. He wanted to colour it with his watercolours. The top is shaped like a cone surmounted by a hemisphere. The entire top is 24.5 cm in height and the diameter of the top is 21 cm. If the surface of the top is painted at the rate of ₹1 per 5 cm 2, then what will be the cost required to paint the entire top?​

Answer 1

area of the top=24.5×21

=514.5 cm²

cost of painting per cm=₹1 per 5cm² = 514.5/5=₹102.9

therefore the cost required to paint the entire top is ₹102.9

hope this helps you...
