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?
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.
