Method 4 Using the Area and Central Angle of a Sector 1 Set up the formula for the area of a sector. y - y_p = m(x - x_p) So, we know the angle $\alpha$ of the arc between the two points -- it's just $\alpha = s/r = 2\pi/x$. The radius of a circle from the area: if you know the area A, the radius is r = (A / ). $$ (I'll use degrees as it is more common for household projects, but can easily be changed into radians as needed), As the angle pointed to by the yellow arrow is $\arctan(\frac{1}{3})\approx 18.43^\circ$, that means the red angles are $90^\circ - \arctan(\frac{1}{3})\approx 71.57^\circ$. Also $R \cdot sin({\alpha \over 2}) = {a \over 2}$, it is also pretty obviously. So, we have a $71.57, 71.57, 36.86$ triangle. The value of is approximately 3.14159. is an irrational number meaning that it cannot be expressed exactly as a fraction (though it is often approximated as ) and its decimal representation never ends or has a permanent repeating pattern. Tap for more steps r = 26 r = 26 (xh)2 +(yk)2 = r2 ( x - h) 2 + ( y - k) 2 = r 2 is the equation form for a circle with r r radius and (h,k) ( h, k) as the center point. Find the radius of a circle $$ Center (or origin): the point within a circle that is equidistant from all other points on the circle. Equation of a Circle Calculator y2 = ?
