Hello from MrBillDoesMath!
Answer:
1283.3
Discussion:
Volume of figure =
volume of cone + volume of cylinder =
(1/3) Pi r^2 h + Pi r^2 h =
(1/3) Pi (7)^2* 7 + Pi (7)^2 * 6 =
Pi * 7^2 ( (1/3) *7 + 6) = => using PI is approx 22/7
(22/7) * 7^2 ( 7/3 + 6) =
(22/7)* 49 (25/3) = 1283.3
Thank you,

12 customers = 9 mins
1 customer = 9 ÷ 12 = 3/4 min
4 customers = 3/4 x 4 = 3 mins
Answer: 3 mins
Answer:
25 seconds
Step-by-step explanation:
Skydiving.
height (in feet) above the earth=h(t)= -16t^2 + 10,000
the time it would take to fall when h is 0
-16t^2 + 10,000=0
-16t^2=-10000
16t^2=10000
t^2=10000/16=625
t=sqrt 625=25 seconds
