Which equations are true?
1 answer:
Answer:
Step-by-step explanation:
1)4.5m+4.7=20m+47
4.5m-20m=47-4.7
-15.5m=42.2
m=-2.72
2)14+21w=7(2+3w)
41+21w=14+21w
21w-21w=14-41
3)49r+35=7(7r+35)
49r+35=49r+245
49r-49r=245-35
4)9(8h-3)=72h-27
72h-27=72h-27
72h-72h=-27+27
5)5.2+5.3t=10+15t
5.3t-15t=10-5.2
-9.7t=4.8
t=4.8/-9.7
t=0.49
6)6f+3.111=18f-33
6f-18f=-33-3.111
-12f=-36.111
f=-36.111/-12
f=3.01

Answer:
V = 1046.9
Step-by-step explanation:
The equation for volume is (4/3)pi r^3
substitute 3.14 in for pi and 6.3 in for r so (4/3)*3.14*6.3^3
