Answer:

\boxed{\sf Radius \ of \ circle = 18 \ ft}

Given:

Circumference of a circle = 36π feet

To Find:

Length of the radius of circle (r).

Step-by-step explanation:

\sf \implies Circumference  \: of \:  a  \: circle =2\pi r \\  \\  \sf \implies 36 \cancel{\pi} = 2 \cancel{\pi }r \\  \\  \sf  \implies \frac{36}{2} =  \frac{ \cancel{2}r}{ \cancel{2}}   \\  \\ \sf \implies \frac{36}{2}  = r \\  \\  \sf \implies r =  \frac{36}{2}  \\  \\  \sf \implies r =  \frac{18 \times \cancel{2}}{ \cancel{2}}  \\  \\  \sf \implies r = 18 \: ft

Sever21 [200]
First, we are going to find the distance traveled by the ship adding the tow distances:
Distance traveled= 24 mi +33 mi=57 mi

Next, we are going to use the Pythagorean theorem to find the distance from a to c:
d^2=24^2+33^2
d^2=576+1089
d^2=1665
d= \sqrt{1665}
d=40.8 mi

Finally, we are going to subtract the two distances:
57 mi -40.8 mi= 16.2 mi

We can conclude that <span>if the ship could have traveled in a straight lime from point a to point c, it could have saved 16.2 miles.</span>
