If a cylinder has a volume of 300 m3 and a radius of 5 m, what is its height (in meters)? (Round your answer to two decimal plac

nevsk [136]

The height of the cylinder is 3.82 m

2. The surface area is 316.5 ft²

The volume is 406.5 ft³

<h3>Calculating volume of a cylinder </h3>

The volume of a cylinder is given by the formula,

V = πr²h

Where V is the volume

r is the radius

and h is the height

From the given information,

V = 300 m³

r = 5 m

h = ?

Putting the parameters into the formula, we get

300 = π × 5² × h

300 = π × 25× h

∴ h = 300/25π

h = 3.82 m

Hence, the height of the cylinder is 3.82 m

Diameter = 6 feet 6 inches = 6.5 feet

∴ Radius = 3.25 feet

Height = 12 feet 3 inches = 12.25 feet

Surface area of a cylinder is given by

Surface area = 2πr(r + h)

Where r is the radius

and h is the height

Surface area = 2π×3.25(3.25 + 12.25)

Surface area = 316.5 ft²

For the volume

V = πr²h

V = π × 3.25² × 12.25

V = 406.5 ft³

Hence, the volume is 406.5 ft³

Translate the sentence into an equation. The difference of a number divided by 3 and 5 is equal to 2 . Use the variable w for th

Whitepunk [10]

Hey there :)

Let us translate each one separately
{ Using w for unknown }

The difference of a number divided by 3 and 5 is 2
'is' is the key-word, meaning you apply the = sign
Difference is subtraction

→ a number divided by 3 - 5 = 2

This is your equation:
→ $\frac{w}{3} -5=2$

Solving for w
Take 5 to the other side
[ When you see subtraction you do addition on the opposite side ]
→ $\frac{w}{3}=2+5$
$\frac{w}{3}=7$

Take 3 to the other side
[ When you see division you do multiplication on the opposite side ]
w = 3 x 7
w = 21
