Basically, I am going to pin a piece of string in the ground y2 feet away from my board and attach a pencil to one end in order to mark the curve that I need to cut. In my sketch, we see that the line of the circle is leaving P1 at a 90-degree angle. In my sketch, we see that the line of the circle is leaving P1 at a 90-degree angle. Our equation of the circle calculator finds not only these values but also the diameter, circumference, and area of the circle all to save you time! The arc itself is not known, only the distance between the two points, but it is known that the arc equals $\frac{2\pi r}{x}$ with $x$ being known. First point: (I'll use degrees as it is more common for household projects, but can easily be changed into radians as needed), As the angle pointed to by the yellow arrow is $\arctan(\frac{1}{3})\approx 18.43^\circ$, that means the red angles are $90^\circ - \arctan(\frac{1}{3})\approx 71.57^\circ$. Note the opposite signs before the second addend, For more information, you can refer to Circle-Circle Intersection and Circles and spheres. The task is relatively easy, but we should take into account the edge cases therefore we should start by calculating the cartesian distance d between two center points, and checking for edge cases by comparing d with radiuses r1 and r2. Method 4 Using the Area and Central Angle of a Sector 1 Set up the formula for the area of a sector. Where does this (supposedly) Gibson quote come from?
