v is the volume of a cylinder ; the radius of the cylinder is 3.5 . the height of the cylinder is 650 % more than the radius . which of the following is true ?
as we see the answers are in form of range we can use approximation volume of cylinder is π r ^ 2 h given π = 22 / 7 and r = 3.5 so r ^ 2 ~ 12 and h = 6.5 * 3.5 ~ 23 so 22 / 7 * 12 * 23 ~ 868 so answer should be d . 700 < v < 900 answer : d
multiply(multiply(const_pi, power(3.5, const_2)), multiply(3.5, divide(650, const_100)))
