If the radius is 2cm and the height is 8cm. How do i start this.

What are you trying to find?

never mine i got the answer i was trying to find Surface area it is 125.7cm^2

To solve this problem, you need to calculate the volume of a cylinder. The formula for finding the volume of a cylinder is V = πr^2h, where V is the volume, r is the radius, and h is the height.

1. Start by identifying the given values:
- Radius (r) = 2cm
- Height (h) = 8cm

2. Substitute the given values into the formula for the volume of a cylinder:
V = π(2^2)(8)

3. Simplify the equation:
V = π(4)(8)
V = 32π

4. As the final answer, you can express the volume as either an exact value using π, or you can approximate it by multiplying 32 by the value of π (approximately 3.14):
- Exact value: V = 32π cubic cm
- Approximate value: V ≈ 100.48 cubic cm
