Answer:
c. right =90 that's the as
45 miles / 1 hour = 45 miles / 60 minutes
Set up a ratio:
45mi/60m = x mi/1m
x = (45×1)÷60 = 0.083333.... mi
Approximately 0.083 miles per minute
We know that
[area of a circle]=pi*r²
r=10 in
[area of a circle]=pi*10²-----> 100*pi in²
if 360° (full circle) has an area of------------------> 100*pi in²
45°-------------------------------> X
X=45*100*pi/360-----> x=12.5*pi in²
the answer is
the option B) 12.5*pi in²
