Step-by-step explanation:
3/5 is the slope, all you have to do is rise over run from one solid point to another solid point and simplify if you have to
It is 0 because of the sin being 0
The calculation for circumference is 2πr or 2 × π (pi=3.14) × radius of a circle
Since the diameter of this circle is 7cm, and the radius is half of the diameter, 7 ÷ 2 = 3.5
So, 2×3.14(π)×3.5=21.98
