First you need to find the circumference of the circle because 1 revolution is 1 length of the circumference. The formula for the circumference is C=2πr or C=πd, if the diameter is 1 meter then the circumference is π1 which is just π, and if it travelled 8000 rotations then that would mean it travelled 8000π, so it travelled 8000π in meters
Answer:
3.5m is 500% of 70 cm and 70 cm is 20% of 3.5m.
Step-by-step explanation:
70 cm = 70cm/100= 0.7m
To solve the first problem use this equation:
3.5/0.7 *100 to get 500%
And to solve the second problem you use the same equation:
0.7/3.5*100 to get 20%
Hope this helps you.
