To find the volume of a cylinder, you need to multiply the area of the base by the height. The base of the cylinder is a circle, so you need to find its area first. The formula for the area of a circle is A = πr², where A is the area and r is the radius.
Given that the width (or diameter) of the cylinder is 4 inches, the radius would be half of that, which is 4/2 = 2 inches.
Next, find the area of the base:
A = πr²
A = π(2)²
A = 4π
The length of the cylinder is given as 5 inches, which will be the height (h) of the cylinder.
Now, to find the volume (V) of the cylinder:
V = A * h
V = 4π * 5
V = 20π
The volume of the cylinder, rounded to the nearest hundredths, is approximately 62.83 cubic inches.
Enter the volume of the cylinder, in cubic inches. Round your answer to the nearest hundredths 4in wide and 5in long
