Answer:
9π units²
Step-by-step explanation:
To obtain an exact answer, use π, not an approximation such as 3.14.
A = πr² is the appropriate formula.
Here,
A = (3)^2·π units², or 9π units²
Answer:
x and z is 16, y is 24
Step-by-step explanation:
divide the bigger measures by 2
10%
since he works 40 hours per week and gets $16 an hour, that would be 16 * 40 which is 640, so that means he needs a commission rate of 10% as 10% of 6400 is 640.

<u>Answer:</u>
The sale price per piece of chicken was $0.69
<u>Step-by-step explanation:</u>
• We have to first calculate the price of 1 piece of chicken when 12 pieces cost $9.48.
Original price per piece = $9.48 ÷ 12
= $0.79
• According to the question the price per piece decreased by $0.10 during the sale.
∴ Sale price per piece = $0.79 - $0.10
= $0.69
Answer:
(−∞,−82)
Step-by-step explanation:
Eighty-two less than r, r−82 is less than <−164.
Now we can solve the inequality by adding 82 to each side.
r−82r−82+82r<−164<−164+82<−82
In interval notation, we write this as (−∞,−82).
