Answer:

207.24 in²

Step-by-step explanation:

When the diameter is 6 inches, the radius is 3 inches, half the diameter.

We can rearrange the formula to make it a little easier to calculate:

SA = 2πR(R +H)

Substituting the given values, R=3, H=8, π=3.14, this becomes ...

SA = 2(3.14)(3)(3+8) = 207.24 . . . . square inches

The surface area of the cylinder is 207.24 square inches.

John is driving around town. When he reaches the gas station, he notes that he has traveled 20 miles. He reaches home 2 hours la

Troyanec [42]

Answer:

$d=5t+20$

Step-by-step explanation:

The equation that will model this situation will be of the form

$d=mt+b$

where $t$ is the time in hours john has traveled since the gas station, and $d$ is the distance.

Now we know that John has already traveled 20 miles when he is at the gas station, this means at $t=0$ , $d=20$ ; or

$20=m(0)+b$

$\boxed{b=20}$

Thus we have

$d=mt+20$ .

Now we need to figure out $m.$

When John reaches home 2 hours later he notes that he has traveled 30 miles, which means he has traveled 30 - 20 = 10 miles; thus we have

$m= \frac{\Delta d}{\Delta t} =\frac{10 miles}{2hours} =5$

$\boxed{m=5}$

Now we have the full equation:

$\boxed{d=5t+20}$

What are the steps to solving this problem K + 8\5 = 1k

DaniilM [7]

-- Subtract K from each side of the equation.

8/5 = 0

-- There is no value for K that can make this a true statement. So the original equation has no solution.
