Simon is filling a cylindrical water dispenser that has a radius of 7 inches and a height of 20 inches. Which of these is the best estimate of the volume of this water dispenser?

Answer 1

The best estimate of the volume of the water dispenser can be calculated using the formula for the volume of a cylinder: V = πr^2h, where r is the radius and h is the height.

Plugging in the values for the radius (7 inches) and height (20 inches), we get:

V = π(7^2)(20)
V = π(49)(20)
V = 3.14 * 980
V ≈ 3077.2 cubic inches

Therefore, the best estimate of the volume of this water dispenser is approximately 3077.2 cubic inches.
