Question

Find the surface area of the cylinder below use the approximation 3.14 for pi

Answer 1

To find the surface area of a cylinder, we need to add the areas of the two bases and the lateral surface area.

The formula for the surface area of a cylinder is:

Surface Area = 2 * (pi * r^2) + 2 * (pi * r * h)

Given that we have the approximation 3.14 for pi, we can substitute it into the formula. Let's assume the radius, r, is 5 cm, and the height, h, is 10 cm.

Surface Area = 2 * (3.14 * (5^2)) + 2 * (3.14 * 5 * 10)
Surface Area = 2 * (3.14 * 25) + 2 * (3.14 * 5 * 10)
Surface Area = 2 * 78.5 + 2 * 157
Surface Area = 157 + 314
Surface Area = 471 cm^2

Therefore, the surface area of the given cylinder is approximately 471 square centimeters.
