Question

Please help i have such a low GPA and i have to get it up so i can get into high school 100 points

Answer 1

Answer:

Well, The volume of the sink shaped like a half sphere is [2000/3] π in^2.

a) The volume of a cylinder is the area of the base * height

For this part the cup has a diameter, d, of 4 in and height, h, of 8 in.

The area of the base is π (d/2)^2 = π (2 in)^2  =  4π in^2.

The volume of the cuo is 4π in^2 * 8 in = 32π in^3.

Then the number of cups to take the volume of [2000 / 3] π in^2 is:

[2000 / 3]π / [32π] = 20.83

Answer: 21 cups.

b) For this part the diameter of the cup is 8 in and the height is 8 in

Then the volume is π (4 in)^2 * 8 in = 128 ⇅ in^3

And the number of cups needed is [2000π/3] / (128π) = 5.2 

Answer: 5 cups. Good Luck!

Answer 2

Answer:

See the 2 answers below.

I would go with 2 scoops but look over it to make sure.

The work:

Volume of cylinder cup = pi r^2 h  = pi 2^2 8 = 32 pi    in^3

volume of sink/volume of cup = number of cups

2000/(3pi)  /   32 pi    = 2 scoops

Or, if you meant the volume  is pi *2000/3      

then  pi*   2000/3  /   32 pi = 21 scoops
