RS Aggarwal Class 10 Solutions Volume and Surface Areas of Solids

Question 1:

rs-aggarwal-class-10-solutions-volume-and-surface-areas-of-solids-19a-q1-1

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

rs-aggarwal-class-10-solutions-volume-and-surface-areas-of-solids-19a-q1-2

Curved surface area of tent

= (curved area of cylinder + curved surface area of cone)

rs-aggarwal-class-10-solutions-volume-and-surface-areas-of-solids-19a-q1-3

Hence, the curved surface area of the tent = 1034

Cost of canvas = Rs.(1034 Ă— 80) = Rs. 82720
