A cylinder has a lateral surface area of about 80 square inches. What is the height of the cylinder if the radius is 4 inches

Height of cylinder is .

Step-by-step explanation:

Here we have , A cylinder has a lateral surface area of about 80 square inches. We need to find What is the height of the cylinder if the radius is 4 inches . Let's find out:

We know that  lateral surface area of cylinder = , Dimensions are as

Putting value of these in we get:

⇒

⇒

⇒

⇒

⇒

⇒

Therefore , Height of cylinder is .

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
