(1)How much water can be held by a cylindrical tank with a radius of 12 feet and a height of 30 feet.
(2)The diameter of a frisbee is 12 inches, what is the area of the frisbee
V = pi r^2 h = pi (144)(30) = 13571.68026 ft^3
1) Use the formula I showed in my last post to you.
2)
Area = pi * r^2
I'll be glad to check your answers.
area of one side is pi r^2 = pi(36) = 113.1 in^2 on the top
same on the bottom so
226.2 for both top and bottom.
To find the answers to these questions, we can use the formulas for the volume of a cylinder and the area of a circle.
(1) To determine the amount of water a cylindrical tank can hold, we need to find its volume. The formula for the volume of a cylinder is V = π * r^2 * h, where V denotes volume, π is a constant approximately equal to 3.14, r represents the radius, and h is the height.
Using this formula, we can substitute the given values:
V = 3.14 * (12 ft)^2 * 30 ft
Calculating this expression gives us the answer:
V ≈ 13572.96 ft^3
Therefore, the cylindrical tank can hold approximately 13,573 cubic feet of water.
(2) To find the area of a frisbee, we need to calculate the area of a circle. The formula for the area of a circle is A = π * r^2, where A denotes area and r represents the radius.
Given that the diameter of the frisbee is 12 inches, we can calculate the radius by dividing the diameter by 2:
Radius (r) = Diameter / 2 = 12 in / 2 = 6 in
Now, we can use this radius value to find the area:
A = 3.14 * (6 in)^2
Calculating this expression gives us the area:
A ≈ 113.04 in^2
Therefore, the area of the frisbee is approximately 113.04 square inches.
