Find the surface area of the cylinder in terms of .

The surface area of the cylinder=  2 π * r^2

Step-by-step explanation:

The surface area of each end and the surface area of the side of the cylinder are added to get surface area of a cylinder.

We know that each end of the cylinder is a circle.

So the surface area of each end of the cylinder is π * r^2

Here, r is the radius of the end

There are two ends, so their combined surface area= 2 π * r^2

The surface area of the cylinder=  2 π * r^2

a) 32pie square meters

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
