Question

Find the height of the cylinder if the surface area is 1097 m square and the radius of the base is 8.2 m

Answer 1

Surface area of cylinder = 2 * 22/7 * r * h

⇒ 1097 = 2 * 22/7 *8.2 * h

⇒1097 * 7/44 * 1/8.2 = h

⇒h=21.28 m square (approx)

Hope it helps !

(well I have taken surface area as CSA)

You can try with TSA if my answer is not correct because this answer looks wrong to me . Just put the formula of TSA if needed and calculate the values like the way I have used above .

Formula of TSA is:-

2 * 22/7 *r (h + r)
