Well I believe that the equation would be
Cairo: y=45+24x
Tarantino: y=30x
The answers would be:
B. Tarantino's cost can be modeled by 30h
D. If the work takes 7 hours , Tarantino's is cheaper

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
