Circle Diagram


GCSE Higher

The diagram shows a circle with equation \(x^2+y^2=13\).


A tangent to the circle touches the circle at the point J. The x-coordinate of J is 2. The tangent intersects the x-axis at K. Find the coordinates of the point K.


GCSE Higher

(a) Find the coordinates of the point at which the curve \(y = k^x\) intersects the y-axis.

The equation of circle \(A\) is \(x^2+y^2=25\). This circle is translated by the vector \( \begin{pmatrix} 0 \\ 4 \\ \end{pmatrix} \) to give circle \(B\).

(b) Draw a sketch of circle \(B\) clearly labelling the points of intersection with the y-axis.


GCSE Higher

A circle with equation \(x^2 + y^2 = 6 \) meets a one of its tangents at point \(S\).

The coordinates of \(S\) are:

$$\left( \frac{\sqrt 5}{3} , \frac{7}{3} \right)$$

Find the equation of the tangent to the circle at the point \(S\).


GCSE Higher

The diagram, not drawn to scale, shows chords joining points on the circumference of a circle. Prove that triangle ADE is similar to triangle BCE.



IB Standard

The following diagram shows a circle with centre O and radius 9 cm.

The points A, B and C lie on the circumference of the circle, and AÔC = 1.2 radians.

(a) Find the length of the arc ABC.

(b) Find the perimeter of the minor sector OAC.

(c) Find the area of the minor sector OAC.


GCSE Higher

Two identical small yellow circles are drawn inside one large circle, as shown in the diagram. The centres of the small circles lie on the diameter of the large circle. The part of the large circle that is outside both small circles is painted red.

Velocity Time Graph

Find the fraction of the large circle that is painted red.


GCSE Higher

(a) The circumference of a circle is \(16 \pi \) cm and its centre is at the origin. Find the equation of the circle.

(b) The line \(12x+ ay = b\) is a tangent at the point (6, 5) to a different circle with centre at the origin. Find the values of a and b.


IB Analysis and Approaches

The diagram shows a circle with a minor sector shaded blue and a major sector shaded yellow.

Circle Sectors

The angle subtended by the major sector at the centre of the circle is six radians.

The perimeter of the major sector is 32.

(a) Find the value of r.

(b) Hence find the exact area of the minor sector.


IB Standard

The diagram below shows an isosceles right-angled triangle and two arcs of circles. The larger arc is part of a circle with its centre at D and the smaller arc is part of a circle with its centre at A.

The right-angled triangle has two sides of length 10cm.

The point D is the midpoint of BC.

Two segments and a triangle

(a) Calculate the area of the red segment.

(b) Calculate the area of the yellow region.
