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. WebOA 2 = AB 2 + OB 2 (by Pythagoras Theorem) 5 2 = 4 2 + OB 2. OB 2 = 5 2 – 4 2 = 25 – 16. OB 2 = 9. OB = √9 = 3. Hence, the radius of the circle = 3 cm. 6. Out of the two concentric circles, the radius of the outer circle is 5 cm and the chord AC of length 8 cm is a tangent to the inner circle. Find the radius of the inner circle. Solution:

"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 given point (2 for x and 11 for y), getting 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is (x+1)^2 + (y+7)^2 = 333 Hope this helps! ( 9 votes) Flag " - Circle theorem 5
