a can of oil 8 inches high and 8 inches in diameter .what is the approximate volume of the can?
recall that a cylinder of radius r and height h has volume
v = πr^2 h
so, that would be
π*16*8 = 128π = 402 in^3
To find the approximate volume of the can, we can use the formula for the volume of a cylinder, which is V = πr^2h.
First, we need to find the radius of the can. The diameter of the can is given as 8 inches, so we divide it by 2 to find the radius: 8 inches ÷ 2 = 4 inches.
Next, we find the height of the can, which is given as 8 inches.
Now we can plug these values into the formula:
V = π(4 inches)^2 * 8 inches
= π * 16 square inches * 8 inches
≈ 3.14 * 16 square inches * 8 inches
≈ 3.14 * 128 cubic inches
≈ 401.92 cubic inches
Therefore, the approximate volume of the can is approximately 401.92 cubic inches.
