Question

Please help with surface area of cylinder

Answer 1

First we find the area of kne circle and then multiply it since we have 2 so 28x3.14 and then we fine then we find the area of the rectangle and then we add it all up to get 60.288

Answer 2

Explanation:

The surface area of a cylinder can be calculated using the formula:

SA = 2πr^2 + 2πrh

where r is the radius of the base of the cylinder, h is the height of the cylinder, and π is approximately equal to 3.14.

Looking at the given diagram, we can see that the height of the cylinder is 10 cm and the radius of the base is 6 cm.

So, substituting these values into the formula:

SA = 2π(6)^2 + 2π(6)(10)

SA = 2π(36) + 2π(60)

SA = 72π + 120π

SA = 192π

Using a calculator, we can approximate this value to:

SA ≈ 602.88 cm^2

Therefore, the surface area of the cylinder is approximately 602.88 cm^2.
