If the diameter of a cylinder is 5 cm and height is 15 cm, what’s the surface area? find the surface area of the cylinder below. Use the approximation 3.14 for pi

Answer 1

The formula for the surface area of a cylinder is given by:

Surface Area = 2πr(r+h)

Where r is the radius of the base and h is the height of the cylinder.

Given that the diameter of the cylinder is 5 cm, we can find the radius by halving the diameter:

Radius = 5 cm / 2 = 2.5 cm

Now, we can substitute the values into the formula:

Surface Area = 2π(2.5 cm)(2.5 cm + 15 cm)

Surface Area = 2π(2.5 cm)(17.5 cm)

Surface Area ≈ 2(3.14)(2.5 cm)(17.5 cm)

Surface Area ≈ (6.28)(2.5 cm)(17.5 cm)

Surface Area ≈ 275.5 cm²

So, the surface area of the cylinder is approximately 275.5 cm².
