Answer 2

Calculation of Surface Area and Volume of a Cylinder

To find the surface area and volume of a cylinder with a height of 20 units and a radius of 5 units, we can use the following formulas:

Surface Area (S): The surface area of a cylinder is given by the formula: S = 2πrh + 2πr^2, where r is the radius and h is the height of the cylinder.

Volume (V): The volume of a cylinder is given by the formula: V = πr^2h, where r is the radius and h is the height of the cylinder.

Let's calculate the surface area and volume using these formulas.

Surface Area (S): Substituting the given values into the formula, we have: S = 2π(5)(20) + 2π(5)^2 S = 2π(100) + 2π(25) S = 200π + 50π S = 250π square units

Volume (V): Substituting the given values into the formula, we have: V = π(5)^2(20) V = π(25)(20) V = 500π cubic units

Therefore, the surface area of the cylinder is 250π square units and the volume of the cylinder is 500π cubic units.
