A sphere and a right cylinder have the same radius and volume. The cylinder has a height of 8 feet. Find the radius.
siniylev [52]

9514 1404 393

Answer:

  6 feet

Step-by-step explanation:

The volume of a cylinder is given by ...

  V = πr^2·h

For a sphere, the volume is ...

  V = 4/3πr^3

You want the volumes to be the same when h=8, so we have ...

  πr^2·8 = 4/3πr^3

Dividing by πr^2, we have ...

  8 = 4/3r

  r = 3/4·8 = 6

The radius is 6 feet.

A grocery store has received a shipment of apples.There are 15 boxes of apples,and each box contains 17 bags of apples. Each bag
gogolik [260]

Answer:

There are 3060 apples in the shipment.

Step-by-step explanation:

Given:

Number of boxes of apples = 15

Each boxes contains = 17 bags of Apples

hence 15 boxes will contains = Number of bags of apples in 15 boxes.

By Using Unitary Method we get;

Number of bags of apples in 15 boxes = 15\times 17= 255 \ bags \ of \ apples

Hence 15 boxes contains = 255 bags of apples.

Also Given:

Each bag contains = 12 apples

255 bags contains = Number of apples in 255 bags

By Using Unitary Method we get;

Number of apples in 255 bags = 255\times12= 3060 \ apples

Hence 255 bags of apples contains = 3060 apples.

Hence There are 3060 apples in the shipment.

Factor the greatest common factor<br>4x²-6x+12​
Serga [27]

Answer:

The solution to this equation could not be determined! (O>O)

Step-by-step explanation:

Simplifying

4x2 + 6x + 12 = 0

Reorder the terms:

12 + 6x + 4x2 = 0

Solving

12 + 6x + 4x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '2'.

2(6 + 3x + 2x2) = 0

Ignore the factor 2, I think this is a 'trick' question !
