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

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...!!

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
