Step-by-step explanation:
Step-by-step explanation:
to find the amount of DVDs on each self =395/5
=75
to find how many tens =395/10=39.5
To answer the question above, convert the given displacement in revolutions to radians. The conversion factor is 1 revolution is equal to 6.28 radians.
(1.9 rev) x (6.28 radians / 1 rev) = 11.932 radians
Thus, the closest to this value is 11.9 and the answer is the second choice.
Answer:
52 m
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 39^2 = 65^2
a^2 + 1521 = 4225
4225 - 1521 = 2704
Square root of 2704 = 52
