The area of the circular base of a cylinder is 36 Square units. The height of the cylinder is 2 units
coldgirl [10]

Answer:

We are asked to solve for the lateral area of the cylinder and the formula is shown below:

Lateral area = 2*pi*r*h

We are also given with the area of the base such as:

Area of the base = 36pi square units

Area of the base = pi*r²

Solving for radius:

36pi = pi*r²

r=6 inches

Solving for the lateral area when height is 2 units:

Lateral area = 2*pi*6*2

Lateral area = 24pi inches²

The answer is the letter "B" 24 square units
