Answer:
Step-by-step explanation:
A=pi*r^2
dA/dt=2*pi*r
1) 24*pi cm^2/min
2)64*pi cm^2/min
You can find the total amount Lewis spent on comic books by multiplying 6 by 13, as he purchased 6 comic books which each cost $13.
6 × $13 = $78
Then, you can subtract that amount from Lewis' earnings from mowing lawns to find how much money he had left after buying the comic books.
$210 - $78 = $132
10 because the ratio is 4/10 and the bottom number is the denominator
