Find the volume and surface area of the right circular cylinder.
(Use 3.14 for a Round to the nearest tenth )
5in radius 2in height
To find the volume of a right circular cylinder, you use the formula V = πr^2h, where r is the radius of the base and h is the height of the cylinder.
Given that the radius is 5 inches and the height is 2 inches, the volume can be calculated as follows:
V = π(5^2)(2)
V ≈ 3.14(25)(2)
V ≈ 3.14(50)
V ≈ 157
So, the volume of the right circular cylinder is approximately 157 cubic inches.
To find the surface area of a right circular cylinder, you use the formula A = 2πrh + 2πr^2, where r is the radius and h is the height.
Given that the radius is 5 inches and the height is 2 inches, the surface area can be calculated as follows:
A = 2π(5)(2) + 2π(5^2)
A ≈ 2(3.14)(10) + 2(3.14)(25)
A ≈ 6.28(10) + 6.28(25)
A ≈ 62.8 + 157
A ≈ 219.8
So, the surface area of the right circular cylinder is approximately 219.8 square inches, rounded to the nearest tenth.
