volume = (1/3) * π * r² * h

= 1/3* 22/7 * (3.5*3.5) * 5 ( 22/7 is the value of π)

=64.1

Answer:

If you need a pi in your answer: 20.417 \pi (rounded to the nearest thousanth)

If you don't: 64.141 (rounded to the nearest thousanth)

Step-by-step explanation:

The formula of the volume of a cone: V = \pi r^2\frac{h}{3}

--> V = Volume, r = Radius, h = Height

In other words, the volume of the cone is the area of the circle x height x 1/3 x pi.

Since the radius of the cone is 3.5, you square that number.

--> (3.5)^2 = 12.25

The height is 5, so h/3 will be 5/3.

The volume = \pi x 12.25 x 5/3

--> 20.416666... \pi

--> 64.14085....

ABCD is a parallelogram. Segment AC = 4x + 10. Find the value of x and y.
valkas [14]

Answer:

The values of x and y in the diagonals of the parallelogram are x=0 and y=5

Step-by-step explanation:

Given that ABCD is a parallelogram

And segment AC=4x+10

From the figure we have the diagonals AC=3x+y and BD=2x+y

By the property of parallelogram the diagonals are congruent

∴ we can equate the diagonals AC=BD

That is 3x+y=2x+y

3x+y-(2x+y)=2x+y-(2x+y)

3x+y-2x-y=2x+y-2x-y

x+0=0 ( by adding the like terms )

∴ x=0

Given that segment AC=4x+10

Substitute x=0  we have AC=4(0)+10

=0+10

=10

∴ AC=10

Now (3x+y)+(2x+y)=10

5x+2y=10

Substitute x=0, 5(0)+2y=10

2y=10

y=\frac{10}{2}

∴ y=5

∴ the values of x and y are x=0 and y=5
