We know that
area of a circle=pi*r²
for r=2 km
area of a circle=pi*2²-----> 12.56 km²
if 360° (full circle) has an area of---------> 12.56 km²
45°---------------------------------> x
x=45*12.56/360-----> x=1.57 km²
the answer is
1.57 km²

Answer:
I would love to help!!
Step-by-step explanation:
157 is equal to half of the circumference...
C=2πr so C/2 is:
πr=157
r=157/π ft
r≈50 ft
The work is the difference between the final and initial kinetic energy:

Substitute your values to get
