Answer:
r = π C , C = 12 − x , t h e n r = π ( 12 − x ) = 12 π − π x
Step-by-step explanation:
So cutting the wire of 12 m in length into two pieces, x and 12-x. The x side will be made into the square so that the square has sides x/4 and an area of (x/4)^2. This means the length of the wire 12-x will be the circumference of the circle. So if: r = π C , C = 12 − x , t h e n r = π ( 12 − x ) = 12 π − π x i hope this is correct

Answer:
D $35.40
Step-by-step explanation:
We need to find 18% of $30 and then add it to the $30 total.
To find a percent of a number, change the percent to a decimal by moving the decimal point two places to the left. Then multiply it by the number.
18% of $30 =
= 18% * $30
= 0.18 * $30
= $5.40
The tip was $5.40. Now we add the tip to the total.
$30 + $5.40 = $35.40
Answer: D $35.40
