The surface area of this cylinder is 21,892.08 square meters. What is the height ?

40.96 will be your height : ) hope it helps

Step-by-step explanation:

have a good day

Definition: The number of square units it takes to exactly cover the surface of a cylinder. Given by the formula:

area=2π r2 + 2πrh

where:

π is Pi, approximately 3.142

r is the radius of the cylinder

h height of the cylinder

Try this Drag the orange dot to resize the cylinder, note how the area is calculated.

Surface area= 2π × 8.02  +  2π × 8.0 × 12.0 = 1005.3

See also: Volume of a cylinder

The surface area of a cylinder can be found by breaking it down into three parts:

The two circles that make up the ends of the cylinder.

The side of the cylinder, which when "unrolled" is a rectangle

Combining these parts we get the formula:

area=2π r2 + 2πrh

where:

π is Pi, approximately 3.142

r is the radius of the cylinder

h height of the cylinder

For a detailed look at how this formula is derived, see Derivation of the surface area of a cylinder

hope it's help you..!!

plz mark as brain list...!!

72 is the answer to this problem

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
