Answer:
6.28 cm
Step-by-step explanation:
The formula for the circumference of a circle with radius r is C = 2*pi*r.
If we let pi = 3.14 and r = 1 cm, then the circumference of this circle is
C = 2(3.14)(1 cm) = 6.28 cm
Make an equation.
.1 X .5 X n = .25 X n - 30
.05n = .25n - 30
30 = .20n
150 = n
