=
2 wholes and 2/
9
V=(4/3)pir^3
SA=4pir^2
so
V=288=(4/3)pir^3
times both sides by 3/4
216=pir^3
divide both sides by pi
216/pi=r^3
cube root both sides
6/(∛pi)=r
sub into other
sa=4pir^2
sa=4pi(6/(∛pi))^2
SA=4pi(36/(∛(pi²)))
SA=144pi/(∛(pi²))
SA=144pi∛pi/pi
SA=144∛pi
SA≈210.901 in²
not sure what option that's supposed to be

Answer:
Brook is faster.
Step-by-step explanation:
1 hour=60 minutes
2 hours=2*60=120 minutes
-------------
7 miles in 30 minutes vs 25 miles in 120 minutes
7/30=0.233...mile per minute
25/120=0.20833...mile per minute
Answer:
56 miles per hour
Step-by-step explanation:
Average speed is found using the formula (total distance)/(total time). The total time is 3 hours. The total distance is 120 + 48 = 168. Therefore, her average speed is 168/3= 56 Miles per hour
