v=(1/3)hpir^2
V=(1/3)9pi1^2=3pi=9.42 cubic inches, so then times 2 for cost to get 18.84 dollars

I think that is A Because u multiplique
Answer:
Step-by-step explanation:
Call T the top
call G the bottom
T G B is a right triangle
37 at B, 90 at G, thus 53 at BTG
TGA is a right triangle
25 at A, 90 at G, thus 65 at ATG
thus 122 at ABT
law of sines:
sin 25 / BT = sin 12/ 57
so BT = 156 meters (first answer)
now angle ABT = 180 - 12 - 25
= 143
so
sin 143 /AT = sin12/57
AT = 164 meters, second answer
5 seconds
because that is the positive zero of that equation
2.73972603 or ... you can round to the nearest tenth... 2.7
