Question

find the volume of cylinder whose CSA is 1188 CM square and height is 18 cm

Answer 1

Curved surface area is :

π × 2r × h

1188 = 22/7 × 2r × 18

1188 = 792/7r

792r = 8316

r = 10.5 cm

Vol = 22/7 × 10.5² × 18 = 6237 cm³

Answer 2

Curved surface area is : $\bf{2πrh}$ (r is radius and h is height )

1188 = 22/7 × 2r × 18

1188 = 792/7r

792r = 8316

r = 10.5 cm

V = 22/7 × 10.5² × 18 = $\bf{6237 cm}$³
