Circles follow ghe equations
(x-h)^2 + (y-k)^2 =r^2
with center (h,k) and radius r
for this circle it would be
(x-7)^2 + (y-4)^2 = 100
Answer:
Step-by-step explanation:
The thing with the arc length formula, s = rt, is that t is the angle in radians. Ours is in degrees, so we have to change it:
36 × 
So the formula we use to solve for r is:

Multiply both sides by 5 over pi to get that
