WebThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the … Web1 aug. 2024 · Find formulas for the circle's radius, diameter, circumference and area , in terms of 'a'. As we've shown above, the circle's radius is equal to the half the length of the square's side, so r=a/2. The diameter is twice the radius, so d=a. The circumference is d ·π, so C=πa. Finally, the area is π·r 2, so A= π·a 2 /4.

WebLet A ( 0, 0), B ( 3, 1), M ( 0, r) (we place the point A ( x 0, y 0) on the origin) Then the distance between A and M (d (A, M)) is r. The distance between B and M is also r, since A and B are both points on the circle. d ( B, M) = ( 3 − 0) 2 + ( 1 − r) 2 = r 2 − 2 r + 10 = r (pythagorean theorem) r 2 = r 2 − 2 r + 10 (square both sides) billy sharp signed photoWebEnter the diameter of a circle.
