PLEASE HELP

Elodia [21]

Answer:

The area of the resulting cross section is $78.5\ m^{2}$

Step-by-step explanation:

we know that

The resulting cross section is a circle congruent with the circle of the base of cylinder

therefore

The area is equal to

$A=\pi r^{2}$

we have

$\pi=3.14$

$r=10/2=5\ m$ -----> the radius is half the diameter

substitute the values

$A=(3.14)(5)^{2}=78.5\ m^{2}$

It took 35 seconds for 5 songs to download to Rebecca’s computer. The next day, it took 42 seconds for 6 songs to download. Writ

sleet_krkn [62]

The equation in point-slope form to represent the time y it took to download x songs is; (y - 35) = 7(x - 5)

Since it took 35 seconds for 5 songs to download

and it took 42 seconds for 6 songs to download

In essence, we can represent the information as;

(5, 35) and (6,42)

To find the slope of the equation; we have;

Slope, m = (42-35)/(6-5)

m = 7

In essence, the equation in point-slope form to represent the time y it took to download x songs is;

(y - 35) = 7(x - 5)
