If you had four rows you would have to put them in 4 groups of 12. 12 * 4=48.
50-48= 2. there will be 2 tiles left over
To isolate r, first divide both sides by pi. That will leave you with r^2=A/pi. Then square root both sides to completely isolate r.
r=<span>√A/pi</span>
The pie it’s self is 6.75, the ice cream is 1.25 and that makes 8 dollars per person which totals up to 32
