Answer:
V = 1200π
Step-by-step explanation:
Volume of a cylinder formula:
Let's find the height of the cylinder by multiplying 20 cm by 3/5.
The radius is 1/2 of the diameter, so:
Substitute 12 for h and 10 for r into the volume formula.
Simplify.
- V = π * 100(12)
- V = π * 1200
The volume of a cylinder, in terms of π, is V = 1200π.
Answer:
43
Step-by-step explanation:
just go backwards so multiply 9 by 4
36
then add 7
43
then to check go 43-7
36-1/4
9
Answer:
3.75+7.5 = 11.25
20 dollars in total how much change.
20 - 11.25 = 8.75
$8.75 change
Answer:
- 4x³ - 33x² + 31x - 3
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
x²(- 4x + 3) + 9x(- 4x + 3) - 1 (- 4x + 3) ← distribute all 3 parenthesis
= - 4x³ + 3x² - 36x² + 27x + 4x - 3 ← collect like terms
= - 4x³ - 33x² + 31x - 3
