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.
