RS Aggarwal Class 10 Solutions Volume and Surface Areas of Solids
Question 1:
Radius of the cylinder = 14 m
And its height = 3 m
Radius of cone = 14 m
And its height = 10.5 m
Let l be the slant height
Curved surface area of tent
= (curved area of cylinder + curved surface area of cone)
Hence, the curved surface area of the tent = 1034
Cost of canvas = Rs.(1034 Ă— 80) = Rs. 82720
