Answer:

36 (Fill 3 in the blank)

Step-by-step explanation:

Given:

Volume of a cylinder = 324 π

Height = 9 cm

The formula to find the volume of a cylinder = Base area * height.

Base is a circle. So the area of a circle = πr^2

Volume of the cylindrical pillar = πr^2 h

324 π = πr^2 . 9

πr^2 = 324 π /9

πr^2 = 36 π

The area of the base = 36 π

Thank you.

analyze this situation and determine how much cookie dough is "wasted" when 3-inch cookies are cut. then have each team member c
Cerrena [4.2K]

Answer:

The result is the same.

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer:

Given the information:

  • square 12 inches wide
  • 3-inch diameter cookies are cut => its radius is: 1.5 inches

Hence we can find some information:

  • The area of the square is: 12^{2}  = 144 square inches
  • The area of a cookies is: r^{2}π = 3.14*1.5^{2} = 7.065 square inches
  • The total number of 3-inch cookies are: 4*4 =16

=> The total area of the cookies is: 16* 7.065 = 113.04 square inches

=> how much cookie dough is "wasted" when 3-inch cookies are cut:

= The area of the square - The total area of the cookies

= 144 - 113.04 = 30.96  square inches

If the diameter is increased to 4 inches => its radius: 2 inches, we have:

  • The area of a cookies is: r^{2}π = 2^{2} *3.14 = 12.56 square inches
  • The total number of 3-inch cookies are: 3*3 =9

=> The total area of the cookies is: 9* 12.56 = 113.04 square inches

=> how much cookie dough is "wasted" when 4-inch cookies are cut:

= The area of the square - The total area of the cookies

= 144 - 113.04 = 30.96  square inches

The result is the same.

What are the coordinates of the pre image of B
garik1379 [7]

Answer:

Point B = (-8 , -2) ⇒ the second answer

Step-by-step explanation:

∵ The figure ABCD is reflected across the x-axis

∴ The sign of y-coordinates of each point will change

Ex: If the point (x , y) reflected across the x-axis

     its image will be (x , -y)

∵ B' = (-8 , 2)

∴ B = (-8 , -2) ⇒ the second answer
