What shows the volume

Svetllana [295]

Answer:

654 1/2 cm³

Step-by-step explanation:

First the volume of the cylinder, the formula for that is πr²h

Radius is half of diameter so 7/2=3.5

3.5^2=12.25

12.25x22/7=38.5

38.5x15=577.5

Now the cone, the formula for this is πr²h/3

It has the same radius as the cylinder so 3.5^2=12.25

12.25x22/7=38.5

38.5x6=231

231/3=77

Now we add them together to find total volume.

577.5+77=654.5

What is the greatest common factor of 12хуб + 60xy? — 24x°у? ?

Liula [17]

The greatest common factor is $12xy$

Explanation:

The given expression is $12xy^6+60xy$

We need to determine the greatest common factor of the given expression.

The greatest common factor of two numbers is the largest number of the two numbers that divides them both.

Hence, from the given expression, let us common out the highest factor that divides the two numbers.

Thus, we have,

$12xy^6+60xy=12xy(y^5+5y)$

Thus, the largest number that divides both the terms is $12xy$

Hence, the greatest common factor of the given expression is $12xy$
