The diameter of a circle subtends an angle of 90∘ at any point on circle. So the angle is 90∘.
A circle has radius 5 cm. A section of its circumference has length π cm. What is the angle subtended by this section at the centre?
A circular wire of diameter 10cm is cut and placed along the circumference of a circle of diameter 1 metre. The angle subtended by the wire at the centre of the circle is equal to
The angle subtended by an arc at the centre is 120 degrees. The angle subtended by it on the circumference is
