volume of a right circular cylinder is 6 o l . if radius of cylinder is doubled , then what will be the increase in volume ?
pi ∗ r ^ 2 ∗ h = 60 double the radius . . . . . pi ∗ ( 2 r ) ^ 2 ∗ h = pi ∗ 4 ∗ r ^ 2 ∗ h = 4 ∗ 60 = 240 important . . we are looking at the increase so 240 - 60 = 180 answer : b
subtract(multiply(multiply(6, const_10), const_4), multiply(6, const_10))
