Where r is the radius of the cylinder and h is the height of the cylinder.

AnnyKZ [126]

<h3>Given:-</h3>

radius = 7 inches
height = 9 inches

$\\ \\$

Surface area of cylinder

$\\ \\$

we know:-

$\bigstar \boxed{ \rm Surface \: Area \: of \: Cylinder=2\pi rh+2\pi {r}^{2} }$

$\\ \\$

So:-

⇢SA of cylinder=2πrh+2πr²

$\\$

⇢SA of cylinder = 2πr(h+r)

$\\$

⇢SA of cylinder = 2 × π × 7(7 + 9)

$\\$

⇢SA of cylinder = 2 × π × 7 (16)

$\\$

⇢SA of cylinder = 2 × π × 112

$\\$

⇢SA of cylinder = 2 × 112 × π

$\\$

⇢SA of cylinder = 224π inches ²

$\\$

.°. Surface Area of cylinder is 224π inches².

irina1246 [14]

Answer=8.6c+13

Meg earns $5.40 per car and $5 in tips. Given the information, Meg's earnings can be shown in the expression '5.40c+5'

Rich earned 3.20 per car and $8 in tips. Given the information, Rich's earnings can be shown with the expression '3.20c+8'

Now lets put the expressions together to see how much they made all together...

5.40c+5+3.20c+8
add 5.40c and 3.20c
8.60c+5+8
add 5 and 8
8.60c+13
or
8.6c+13
