Question : A hemispherical bowl has a 3.5 cm radius. It is to be painted inside as well as outside. The cost of painting it at the rate of Rs. 5 per 10 sq. cm will be:

Option 1: Rs. 77

Option 2:  Rs. 100

Option 3: Rs. 175

Option 4: Rs. 50

Team Careers360 19th Jan, 2024

Correct Answer: Rs. 77


Solution : Given: Radius ($r$) = 3.5 cm
Outer surface area of hemisphere = $2\pi r^2$
Inner surface area of hemisphere = $2\pi r^2$ (here width is negligible)
Surface area of both sides = $2\pi r^2+2\pi r^2 = 4\pi r^2$
= $4×\frac{22}{7}×3.5×3.5$
= 154 cm$^2$
