a cylinder has a base diameter of 14 inches and a height of 18 inches . what is the volume of the cylinder
v = pi r^2 h
plug in your numbers
To find the volume of a cylinder, you can use the formula:
V = π * r^2 * h
where:
V = volume
π (pi) = approximately 3.14159
r = radius of the base
h = height of the cylinder
First, we need to find the radius of the base. The diameter is given as 14 inches, so we can divide it by 2 to find the radius:
Radius (r) = Diameter / 2 = 14 inches / 2 = 7 inches
Now, we have all the necessary values to calculate the volume:
V = π * (7 inches)^2 * 18 inches
Calculating further:
V = 3.14159 * (49 square inches) * 18 inches
V = 3.14159 * 882 square inches * 18 inches
V = 49.29 * 18 cubic inches
V ≈ 887.04 cubic inches
Therefore, the volume of the cylinder is approximately 887.04 cubic inches.
