Answer:

B

Step-by-step explanation:

What you have to do is to find the volume of both forms and add them together.

So the formula for area of a cone (the top half of the pylon) is:

V=πr^2(h/3)

So now we plug our values in.

V=π1^2(2/3)

Simplify.

V=2/3π

Next, we find the volume of the cylinder.

The formuhe formla for this is:

V=πr^2h

So again, we plug the values in

V=π1^2(3)

Simplify.

V=3π

Now we add the volume of the cylinder with the volume of the cone.

2/3π+3π=3 2/3π

Therefore, you need 2/3π cubic feet of concrete.

Darrel has 36 daisies and 54 roses. He wants to put an equal number of daisies and roses into vases. What is the GREATEST number
castortr0y [4]

Answer:

18 number of daisies and 18 number of roses

Step-by-step explanation:

We are told Darrel has 36 daisies and 54 roses.

And that He wants to put an equal number of daisies and roses into vases.

To get the equal number, it means we have to find the greatest common factor of 36 and 54.

Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

Factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54

From the factors of both 36 and 54, the greatest common factor to both of them is 18.

Thus, the GREATEST number of daisies and roses Darrel can put in each vase is 18 each

\A and \B are supplementary angles. If m\A= (3x – 23) and m
mrs_skeptik [129]

2 supplementary angles when added together need to equal 180 degrees.

Add:

3x-23 + 2x-12 = 180

Simplify:

5x -35 = 180

Add 35 to both sides:

5x = 215

Divide both sides by 5:

X = 43

Now replace x with 43 in the equation for angle b:

2(43) -12 = 86-12 = 74 degrees

Angle B = 74 degrees
