Question

the area of the base of a right circular is 616m2 and its height is 2. 5cm. find the volumn of cylinder​

Answer 1

Answer

:Area of base of right circular cylinder = 616 cm²

Height of cylinder = 2.5 cm

Let the radius of cylinder be ‘r’ cm By using the formula,

Area of base of right circular cylinder = πr2

So, πr2 = 616 22/7 × r2 = 616 r2 = 616 × 7/22 = 196 r = √196 = 14cm

∴ Curved surface area of cylinder = 2πrh = 2 × 22/7 × 14 × 2.5 = 220 cm²

hope it helps
