Answer: 244. 92 cm

Step-by-step explanation:

The surface area formula for a cylinder is written as SA = 2πrh + 2πr^2

The dimensions of the cylinder has a length of 6 cm diameter and a height of 10 cm. Radius is basically half of the diameter, so 3 cm. We use these numbers to substitute into the formula.

SA = 2π(3)(10) + 2π3^2

SA = 2π(30) + 2π(9)

SA = 60π + 18π

SA = 78π

SA = 245.044 cm

244.92 is close enough to 245.004, so 244.92 is the answer.
