A circle of radius 5 cm is translated through a distance of 10 cm. What is the new radius of the circle?
10 cm
20 cm
5 cm
15 cm
Translation doesn't change the shape, size or colour of the object, it just changes its position. So, the radius remains same.
If AB = 10 cm & DB = 40 cm (diameter). What is the radius of curvature & focal length?
If AB = 10 cm and DB = 40 cm (diameter). What is the radius of curvature and focal length?
What will be the radius of a circle with diameter 20cm?
A tangent is drawn at a point P on a circle. A line through the centre O of a circle of radius 7 cm cuts the tangent at Q such that PQ = 24 cm. Find OQ.
