The hemispherical dome of a building needs to be painted. If the circumference of the base of dome is 17.6 m, find the cost of painting it, given the cost of painting is Rs.5 Per 100 cm ^(2)

The outer Surface of the cube of side 6 m is painted. If the cost of painting is Rs. 1 per 100 " cm"^2 . Find the total cost of painting the cube.

A cubical container of side 6.5 m is to be painted on the entire outer surface. Find the area to be painted and the total cost of painting it at the rate of ₹ 24 per m^(2) .

A bus stop is barricaded from the remaining part of the road, by using 50 hollow cones made of recycled card-board. Each cone has a base diameter of 40cm and height 1m. If the outer side of each of the cones is to be painted and the cost of painting is Rs. 12 per m^2 , what will be the cost of painting all these cones (U s epi=3. 14a n dsqrt(1. 04)=1. 02))

A bus stop is barricaded from the remaining part of the road, by using 50 hollow cones made of recycled cardboard. Each cone has a base diameter of 40 cm and height 1 m. If the outer side of each of the cones is to be painted and the cost of painting is Rs 12 per m^2 , what will be the cost of painting all these cones (use pi = 3.14 , and take sqrt(1.04)=1.02 ) ?
