Find the surface area of a cylinder with the radius of 6 in the height of 14 in. Use the approximation 3.14 for pi. Formula SA equals 2πr^2 + 2πrh
The formula for the surface area of the cylinder is SA = 2πr^2 + 2πrh, where r is the radius and h is the height.
Given:
Radius (r) = 6 in
Height (h) = 14 in
Substituting the values into the formula:
SA = 2π(6^2) + 2π(6)(14)
Simplifying:
SA = 2π(36) + 2π(84)
SA = 72π + 168π
Approximating π as 3.14:
SA ≈ 72(3.14) + 168(3.14)
SA ≈ 226.08 + 527.52
SA ≈ 753.6
Therefore, the surface area of the cylinder is approximately 753.6 square inches.
