4 0

it would be 5.0 I think because it is just taking .9 and giving it to 4 which makes it round to 5.

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.

How do you find the length of the short leg on a 30°-60°-90° triangle when all you have is the long leg?

tatyana61 [14]

The ratios of the sides
hypotnuse=2x
x=short leg (oposite 30)
x√3=long leg (oposite 60)

long leg=x√3
to find x, divide by √3
longleg/√3=short leg=x
rationalize denomenator, times √3/√3
(longleg√3)/3=short leg

the legnth of the short leg is
(longleg√3)/3
