A square pyramid is cut, open and laid flat as in the figure below. What is the surface area of this pyramid ?
In the trapezium ABCD, AB=3 centimetres, BD=5 centimetres, BC=6 centimetres. The area of the trapezium is:
In the figure, BC is a chord and PA is a tangent to the circle. PB=4 centimetres, PA=6 centimetres, the length of the chord BC is:
In the figure, O is the centre of the circle and PA is a tangent to it. The point P is 10 centimetres away from the centre of the circle. The diameter of the circle is 10 centimetres. <POA=
