just listen to ur teacher and u will learn something LOL
Formula for circumference: C = 2pi*r
This becomes 201 cm = 2(3.14) r
Divide both sides of this eqn by 6.28:
201
------- = r = 32 cm (approx).
6.28
I think you find 18.63% of $835 and then you get your answer. I am pretty sure it is $155.56, hope this helps.
flooring a value, simply means, dropping it to the closest integer, so for the floor function or ⌊x⌋, that means
⌊ 2.5 ⌋ = 2
⌊ 2.00000001 ⌋ = 2
⌊ 2.999999999999⌋ = 2
⌊ -2.0000000001⌋ = -3
⌊ -2.999999999999⌋ = -3
let's recall that on the negative side of the number line, the farther from 0, the smaller, so -1,000,000 is a tiny number compared to the much larger -1.
⌊ -5.2 ⌋ = -6.
