Answer:
Volume of bottom of cylinder = Volume of entire cylinder - Volume of top of cylinder
Step-by-step explanation:
Here we have the volume of a cylinder given by
Volume of a cylinder = πr²h
Where the cylinder is cut by a plane into portions of heights, bottom a and top b we have
Height of bottom of is then
Height = h - b
Therefore, volume of bottom of cylinder = π·r²h = π·r²(h - b)
Volume of bottom of cylinder = π·r²·h - π·r²b
Volume of bottom of cylinder = Volume of entire cylinder - Volume of top of cylinder.
Answer:
4 4/27 sq inches
Step-by-step explanation:
the area is 2⅔ × 1 5/9 = 8/3 × 14/9
= 112/27 = 4 4/27
Answer: 42 - 8x
Step-by-step explanation:
Here is the complete question:
Jessica had $15. She bought 3 apples for x dollars each. Levi had $27 and bought 5 apples for x dollars each. Which expression represents how much money both Jessica and Levi have left altogether?
Select one:
27 – 5x
42 – 8x
12 – 2x
39 – 3x
From the question, Jessica had $15. She bought 3 apples for x dollars each. This means she had:
15 - (3 × x) = 15 - 3x
Levi had $27 and bought 5 apples for x dollars each. Levi will have:
27 - (5 × x) = 27 - 5x
The amount they'll have altogether will be the addition of their amount left. This will be:
15 - 3x + 27 - 5x
= 15 + 27 - 3x - 5x
= 42 - 8x
Its about 13.64% multiply 4.75 by 100 then divide by 5.5 then subtract that number from 100
