Using the cube formula for volume I got V=3.38cm^3
This means that 3/10 are red and that 7/10 are red, so 7/10(80) = 56blue marbles and 3/10(80)= 24red marbles
A + E + N = 122
E = 2N
A = 7 + E....A = 7 + 2N
(7 + 2N) + 2N + N = 122
5N + 7 = 122
5N = 122 - 7
5N = 115
N = 115/5
N = 23 <== North America
E = 2N
E = 2(23)
E = 46 <== Europe
A = 7 + E
A = 7 + 46
A = 53 <=== Africa
Answer:
24ft
Step-by-step explanation:
So you need to find the circumfrnce and I am 3 for pi
so 3(4)2=24ft
