The first one because 3*2 =6 and 4.5*2= 9 and 4*2=8 and they are all the same as the other triangle
2x+5=50
-5 -5
—————-
2x = 45
Divide by 2
45/2 = 22.5
I hope this makes sense
Answer:
Ball Bearing Volume = (4 / 3) * PI * radius ^3
Volume = (4 / 3) * 3.14159265 * (.35)^3
Volume = (4 / 3) * 3.14159265 * 0.042875
Volume = 0.17959438 cc
1 cc of steel = 7.8 g
Volume of 1 kg of steel = 1,000 cc / 7.8 g per cc
1 kg = 128.205 cc
Number of ball bearings we can make = 128.205 / 0.17959438
Equals 713.86
