To find the volume of a cylinder, we use the formula:
V = πr^2h
where V represents the volume, r represents the radius, and h represents the height.
Given that the radius, r, is 3 inches and the height, h, is 1 inch, we can substitute these values into the formula:
V = 3.14 * (3^2) * 1
V = 3.14 * 9 * 1
V = 28.26 cubic inches (rounded to the nearest tenth)
To find the surface area of a cylinder, we use the formula:
A = 2πrh + 2πr^2
where A represents the surface area, r represents the radius, and h represents the height.
Again, substituting the given values into the formula:
A = 2 * 3.14 * 3 * 1 + 2 * 3.14 * (3^2)
A = 18.84 + 56.52
A = 75.36 square inches (rounded to the nearest tenth)
Therefore, the volume of the right circular cylinder is approximately 28.3 cubic inches, and the surface area is approximately 75.4 square inches.
