Find the radius of a circle of diameter 10 cm.
Given that
The length of the diameter of a circle = 10 cm
We know that, radius of a circle = Diameter2
On substituting the values we get:
Radius of circle = 102=5 cm
If AB = 10 cm & DB = 40 cm (diameter). What is the radius of curvature & focal length?
The radius of a circle is 17.0 cm and the length of perpendicular drawn from its centre to a chord is 8.0 cm. Calculate the length of the chord.
The length of the tangent drawn from a point 8 cm away from the centre of a circle, of radius 6 cm, is :
What will be the diameter of a circle of radius 18 cm?
