The answer is equal to 9threes because 3+3+3=9 and 6*3=18 which is a multiple of three and alos 3,6 and then 9.

PLEASE HELP! BRAINLIEST!!!!!!! PLEASE

Hello!

First you have to find the volume of the cylinder

To find the volume of a cylinder you use the equation

$V = \pi r^{2} h$

V is volume
r is radius
h is height

Put in the values you know and 3.14 for pi

$V = 3.14 * 3^{2} * 7$

Square the number

V = 3.14 * 9 * 7

Multiply

V = 197.82
------------------------------------------------------------------------------------------------------
Next you find the volume of the sphere

To find the volume of a sphere you use the equation

$V = \frac{4}{3} \pi r^{3}$

V is volume
r is radius

Put in the values you know and 3.14 for pi

$V = \frac{4}{3} * 3.14 * 3^{3}$

Cube the number

$V = \frac{4}{3} * 3.14 * 27$

Multiply

V = 113.04
------------------------------------------------------------------------------------------------------
Finally you subtract the two volumes from each other

197.82 - 113.04 = 84.78
------------------------------------------------------------------------------------------------------
The answer is C)84.78

Hope this helps!

What is the diameter of the cylinder if the height is 13, and the volume is 1256? Use 3.14 for pi.

Sergio039 [100]

Volume of a cylinder = πr²h

1256 = (3.14) x (r)² x (13)

1256 = 40.82r²

r² = 1256 ÷ 40.82

r² = 30.769

r = √30.69

r = 5.547

Diameter = Radius x 2

Diameter = 5.547 x 2

Diameter = 11.09 units (nearest hundredth)

The perimeter of a rectangular deck measured 130 m. What are the possible

fomenos

Answer:

The possible dimensions of the deck can be anything that adds up to be 130 m.

Step-by-step explanation:

<em>The perimeter could be 1m x 64m.</em>

Two sides would be 1m each (so 2m total) and the other two sides would be 64m each (128m total). 2 + 128 = 130m.

<em>The perimeter could be 15m x 50m.</em>

Two sides would be 15m each (so 30m total) and the other two sides would be 50m each (100m total). 30 + 100 = 130m.
