You would subtract the the amount painted from 500.
500-193=307
They have to paint 307 more.
To answer this question you should know what to do to change the polar coordinates to rectangular ones: x = rcos (θ)
y = rsen (θ)
So for r = -2 and θ = 2π we have
x = -2cos (2π)
x = -2
y = -2sen (2π)
y = 0
Finally the equivalent point in Cartesian coordinates is the point:
(-2 0)
The correct answer is option B
Arithmetic is about computation of specific numbers. Algebra is about what is true in general for all numbers, all whole numbers, all integers, etc.
31/15 is the simplified fraction. Hope this helped
14=42
42 in cubed
volume is length x width x height
you already have the area of the base of the shape so all you need to do is times is by the height to find the volume
