WebThe diagram shows a circle with centre O and radius r cm. Points A and B lie on TU the circle and angle AOB = π/4 radians. The tangent to the circle at A intersects the straight line through O and B at the point C. iii) The area of triangle OAC. The area of the shaded region is 100 cm². b) Find the value of r. WebSep 15, 2024 · Theorem 2.5. For any triangle ABC, the radius R of its circumscribed circle is given by: 2R = a sinA = b sin B = c sin C. Note: For a circle of diameter 1, this means a = sin A, b = sinB, and c = sinC .) To prove this, let O be the center of the circumscribed circle for a triangle ABC.

How to Determine the Geometry of a Circle - ThoughtCo

WebA circle is all points in a plane that are a fixed distance from a given point on the plane. The given point is called the center, and the fixed distance is called the radius. The standard form of the equation of a circle with center (h,k) ( h, k) and radius r r is (x−h)2+(y−k)2 = r2 ( x − h) 2 + ( y − k) 2 = r 2.

WebFeb 26, 2010 · r is the radius of the circle. Putting it into standard form we get: *Plug in 0 for h, 0 for k, and 10 for r *10 squared is 100 *Standard form of circle with center (0, 0) and radius 10 Generally, when you have an expression where you are subtracting 0, you can simplify it by not writing the - 0. ... WebExample 1: In the given circle, O is the center, and AB which is the chord of circle is 16 cm. Find the length of AD if OM is the radius of the circle. Solution: We know that the radius of a circle is always perpendicular to the chord of a circle and it acts as a perpendicular bisector. Therefore, AD = 1/2 × AB = 16/2 = 8. Therefore, AD = 8 cm.
