The LCM of 4,10 and 12 is 60.
You can fit 153 flowers in a circle with the diameter of 14. You find the area of the circle by doing pi times 7 squared.
Answer:
x2 + y2 = r2, and this is the equation of a circle of radius r whose center is the origin O(0, 0). The equation of a circle of radius r and center the origin is x2 + y2 = r2.
I think this is the answer.
