I think the answer may be 2.1 I'm not 100 percent sure
0.01388888888 this but shorten it would be. .0138
For cylinder
h=2m
d=5×2m=10m
so r=d/2=10/2=5m
so volume of cylinder=pi×r^2×h
=3.14×5×5×2
=3.14×50
=157m^2
Answer:
22 ok i eo
Step-by-step explanation:
ok i will explaim
I'm gonna calculate by the area of pizza to see how much food you get for 10 and 20 dollars
A...area
r...radius
d...diameter
d1=12 r1=6
d2=18 r2=9
A1=r1^2×3.14
A1=6^2×3.14
A1=36×3.14
A1=113.04
A2=r2^2×3.13
A2=9^2×3.14
A2=81×3.14
A2=254.34
if you bought 2, 12 diameter pizzas for 20 dollars you would get 226.08 area od food,still less if you bought 1, 18 diameter pizza for 20 dollars. because 223.08 < 254.34
