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. Formula: SA=2πr2 + 2πrh
The formula for the surface area of a cylinder is SA = 2πr^2 + 2πrh, where r is the radius and h is the height.
First, let's calculate 2πr^2:
2π(6)^2
= 2π(36)
= 72π
Next, let's calculate 2πrh:
2π(6)(14)
= 12π(14)
= 168π
Now, let's find the sum of these two parts to get the total surface area:
72π + 168π
= 240π
Approximating pi to 3.14:
240π
≈ 240(3.14)
≈ 753.6
Therefore, the surface area of the cylinder is approximately 753.6 square inches.
