hemisphere is built. The diameter of the dome is 14 m.
How much will it cost if the dome is to be painted at
the cost of Rs 20 per square meter?

Answer 1

HEYA MATE !

D=14m

R=7m

CSA of hemisphere=2πr²

=2×22/7×7×7

=2×22×7

=44×7m²

=308m²

Cost of painting 1m²=₹20

Cost of painting 308m²=308×20=₹6160
