Question

The diameter of the cylinder is (6x-8) in. And the height of the cylinder is (11x+10) in. Find the volume of the cylinder when x=7

Answer 1

The answer is 25,143pi

Answer 2

78949

Explanation:

v = Bh = πr²h = 3.14 x (3x - 4)² x (11x + 10) x = 7

= 3.14 x (21 - 4)² x (77 + 10)

= 3.14 x 289 x 87

= 78949
