SA=pi r s+ pi r^2 , solve for s
SA-pi r^2=pi r s
(SA- pi r^2)/pi*r=s
can be written also
<u>SA</u> - r= s<u>
</u>pi*r<u>
</u>
C because he obviously doubled it and 3 hours doubled is 6 hours
Just transpose the 5 to the right side of 18 so it will look like this, /x/ = 18 - 5
Then get the difference and it would be 13. So to check this out if it is correct, substitute x for the value of 13 and it will look like this.
13 + 5 = 18
I hope my answer helped you.

Answer:
- 63 mph
- 3 donut holes per kid
- $0.70 per pound
- $2.25 per km
Step-by-step explanation:
In this context, "per" and "for" mean "divided by."
- 630 mi/(10 h) = 63 mi/h
- (24 dh)/(8 kid) = 3 dh/kid
- $3.50/(5 lb) = $0.70 /lb
- $32/(14 2/9 km) = $32/(128/9 km) = $(9/4)/km = $2.25 /km
