Answer:
It's (-1.5,-5.5)
Step-by-step explanation:
SA=4pir^2
V=(4/3)hpir^2
given
SA=36pi
36pi=4pir^2
divide by 4pi
9=r^2
sqrt both sides
3=r
v=(4/3)pir^3
v=(4/3)pi3^3
V=4pi9
v=36pi
36pi cubic feet
An 544.5
Step-by-step explanation:
2t+2d+2c=30
2(8.50)+2(3.50)+2(3.00)=$30
t representing tickets d representing drinks c representing candy
the answer really depends on how much of each item they buy
if they bought more than 2 of each just change the 2 to the number of items bought
