what is the volume of the cone with height of 9mm and the radius of 7mm?
The volume of a cone is given by the formula V = (1/3)πr^2h, where r is the radius, h is the height, and π is a constant equal to approximately 3.14.
Plugging in the values given in the problem, we get:
V = (1/3)π(7mm)^2(9mm)
V = (1/3)π(49mm^2)(9mm)
V = (1/3)π(441mm^2)(9mm)
V ≈ 4,160.67 mm^3
Therefore, the volume of the cone is approximately 4,160.67 cubic millimeters.
