O is the centre of this circle. Tangent drawn from a point P, touches the circle at Q. If PQ = 24 cm and OQ = 10 cm, then what is the value of OP? 

PK is the median and M is a centroid of triangle PQR. If PK is 15 cm, then find length of PM?

In ΔABC, if G is the centroid and AD is a median with length 9 cm, then the length of AG is:

The in-radius of an equilateral triangle is of length 3 cm. Then the length of each of its medians is 

A cube has sides that are 4 cm each, and the dimensions of a cuboid are 2cm x 3cm x 4cm. Find the positive difference between the volume of the cube and that of the cuboid.

AB is a diameter of a circle with centre O. The tangents at C meets AB produced at Q. If ∠CAB = 34°, then measure of ∠CBA is

ABC is a triangle in which DE || BC and AD: DB = 5: 4. Then DE: BC is

ABCD is a cyclic quadrilateral. AB and DC when produced meet at P, If PA 8 cm, PB = 6, PC = 4 cm, then the length (in cm) of PD is
