C = 3.14 × r
r = 10 cm
C = 3.14 × 10 = 31.4 cm
Hope it helped!
It is always increasing.
To find increasing and decreasing intervals, we need to find where our first derivative is greater than or less than zero. If our first derivative is positive, our original function is increasing and if g'(x) is negative, g(x) is decreasing.
I dont quite undeerstand but the gcf for both are..., if that helps is 4 because
30:2*2*2*2*2
22:2*2 5
40/3 or 13.333333- your welcome
