Question

find the volume of a cylinder whose height is 2m and area of the base os 250m*2.

Answer 1

volume of cylinder is πr^2h i.e area of base ×height eqauls to 250× 2= 500m^3

Answer 2

Base circle area = πr²

250 = 22/7 × r²

r² = 250 × 7 / 22

r² = 79.5

r = √79.5

r = 8.9 m

h = 2 m

Volume of cylinder = πr²h

= 22/7 × 8.9² × 2

= 497.89 m³
