The measure of the angles of a triangle are in the ratio 2 : 7 : 11. Measures of angles are : 

A copper wire is bent in the form of an equilateral triangle and has area 121√3 cm² . If the same wire is bent into the form of a circle, the area (in cm²) enclosed by the wire is (Take pi= 22 /7)

PA and PB are two tangents to a circle with center o from a point P outside the circle. A and B are points on the circle. If ∠OAB = 35° than ∠APB is equal to: 

In ∆ ABC measure of angle B is 90⁰. If cos A = $$ 5\over 13 $$ and AB = 10 Then what is the length of side BC ?

If the curved surface area of a cylinder is 126π cm² and its height is 14 cm, what is the volume of the cylinder?

A semi-circular sheet of metal of diameter 28 cm. is bent into an open conical cup. The depth of the cup is approximately 

If the length of one side and the diagonal of a rectangle are 7 cm and 25 cm respectively, then find its perimeter (in cm).

The lateral surface area of a cylinder is 792cm². If its height is 14cm, then its volume (in cm³) is? [Take π = 22/7 ]
