Answer:
Step-by-step explanation:
circumference for A=2π×12=24π
linear velocity=24π÷6=4π cm/sec
circumference for B=2π×15=30π
linear velocity=30π÷6=5π cm/sec
6.1 is the answer wry simple and easy
Answer:
486 sq. in
Step-by-step explanation:
Find the area of one face
Area = s^2
s = 9 in
Area = 9^2
Area = 81
Area 6 sides
There are 6 sides to a cube. So if you have the area of 1 side, you need only multiply by 6 to get the area of the cube
Area = 6 * 81
Area = 486
So there are 152 machines. After 24 hours of operation they make 1.47x
So we know that 1.47x = 14,700,000.
Now we just divide this by 24.
14700000/24=612,500
Now thats the total, we need to divide by 152 since there are that many machines that make up that number.
612,500/152 about 4029
So your rate is 4029 per hour per machine.
