Answer:

Step-by-step explanation:
The formula of a volume of a cylinder:

r - radius
H - height
We have r = 3in and H = 9in. Substitue:

5/16 multiply the denominator by 2 and add 1 to the numerator
9/32 multiply the denominator by 4 and add 1 to the numerator
10/32 multiply the denominator by 4 and add 2 to the numerator
If you mean equal payments each week like 30x = 2730 then it would be $91 per week for the 30 weeks to pay it
Answer:
y² + 8y + 16
Step-by-step explanation:
Given
(y + 4)²
= (y + 4)(y + 4)
Each term in the second parenthesis is multiplied by each term in the first parenthesis, that is
y(y + 4) + 4(y + 4) ← distribute both parenthesis
= y² + 4y + 4y + 16 ← collect like terms
= y² + 8y + 16
