Answer: πr^2
Step-by-step explanation:
π is pie which is about 3.14
but you need to find the radius and square it is multiply it by itself (Example radius = 2 so 2x2=4)
then multiply the radius squared by π(pie) which is 3.14 or use a calculator.

Step-by-step explanation:
1) Collect like terms.

2) Simplify.

So, therefor, the answer is -17y - 16z + 4.
<span>from the whole price,
15% of this price is equal to $18.00.
therefore if 15 % equals $18.00
then 100% is the original price therefore 100 % = 18.00 / 15 % x 100% = $120 therefore original price = $120</span>
Answer:
10x + 3
