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...!!

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
