In a circle with center o
WebJul 4, 2024 · The length of the tangent from an external point A on a circle with centre O is: Q8. The area of a sector of a circle is 66 cm2 and the angle of the sector is 60°. Find the radius of the circle. Q9. The length of the tangent to a circle from a point P is 15 cm. Point P is 17 cm away from the centre. What is the radius of the circle? Q10. WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4.
