Help her in making project by answering the following questions :

Q. Find the cost of painting the dome, given the cost of painting is ₹ 100 per cm2.

Detailed Solution for Test: Surface Area & Volumes- Case Based Type Questions - Question 9
Curved surface area of hemispherical dome

= 968p m2

Cost of painting 100 cm2 = ₹ 10

Cost of painting 1 m2 = ₹ 1000

Thus, cost of painting the dome

= ₹ 1000 × 968π cm2

= ₹ 968000π
