find the surface area of a cylinder with a radius of 6 inches and a height of 14 inches use the approximation 3.14 for pi
The formula to calculate the surface area of a cylinder is:
Surface Area = 2πr(r + h)
Given:
Radius (r) = 6 inches
Height (h) = 14 inches
Using the approximation 3.14 for π:
Surface Area ≈ 2 * 3.14 * 6(6 + 14)
Calculating the expression inside the parentheses:
Surface Area ≈ 2 * 3.14 * 6 * 20
Multiplying:
Surface Area ≈ 753.6 square inches
Therefore, the surface area of the cylinder is approximately 753.6 square inches.
