The formula for the surface area of a cylinder is 2πrh + 2πr^2, where r is the radius and h is the height.
Given:
r = 1
h = 3
Plugging in the values into the formula:
Surface area = 2π(1)(3) + 2π(1^2)
Surface area = 2π(3) + 2π
Surface area = 6π + 2π
Surface area = 8π
Approximating pi as 3.14:
Surface area ≈ 8(3.14)
Surface area ≈ 25.12
Therefore, the surface area of the cylinder is approximately 25.12 square units.
Find the surface area of the cylinder below. Use the approximation 3.14 for pi.
Radius: 1
Height: 3
