Answer:
its 7
Step-by-step explanation:
Interior angle add up to 360, so you add
(a+10) + (3a+10) + (5a-10) + (3a-10) = 12a
12a =360
a= 30
30+10=40
3(30)+10=100
5(30)-10=140
3(30)-10=80
You can double check they're correct by doing 40+100+140+80, which equals 360.
V=hpir²
h=8
d=2r
d/2=r
5/2=2.5=r
V=8pi2.5²
V=8pi6.25
V=50pi
aprox pi=3.14
V=50 times 3.14
V=157 in³
157 cubic inches
Hey there!
63 = 13 + 2P subtract 13 from both sides
50 = 2P divide both sides by 2
25 = P
So the cost of one pass = $25
Hope this helps!
