Answer 1

Answer:

circumference of base of the dome = 17.6 m Therefore 17.6 = 2πr

So, The radius of the dome =17.6×

2×22

7

m

= 2.8 m

The curved surface area of the dome =2πr

2

=2×

7

22

×2.8×2.8m

2

=49.28m

2

Now, cost of painting 100 cm

2

is Rs. 5

So, cost of painting 1 m

2

= Rs. 500

Therefore, cost of painting the whole dome

=Rs.500×49.28

=Rs.24640
