A circle is written as x^2+y^2=r^2. if the center is at the origin, it doesnt need to be vertically or horizontally. you would square the radius, 12, and set it equal to x^2+y^2. the final equation is x^2+y^2=144
Answer:
the second graph in the picture shows the equation
Answer:
84.78
Step-by-step explanation:
A=π r²
6*6(r²)=36
36*3.14(π)=113.04
113.04*3/4(it is 3/4 of a circle)=339.12/4
339.12/4=84.78
180/7=25.71428571 per hour
25.71428571/60=0.428571428 (per second
0.428571428/60=0.007142857 (per minute) miles
in foot it is 0.000595238
