Circles Exercise 10.7 – Question
- Draw two circles of radii 5 cm and 2 c touching externally.
- Construct two circles of radii 4.5 cm and 2.5 cm whose centres are at 7 cm apart.
- Draw two circles of radii 4 cm and 2.5 cm touching internally. Measure and verify the distance between their centres.
- Distance between the centres of two circles touching internally is 2 cm. If the radius of one of the circles is 4.8 cm, find the radius of the other side and hence draw the touching circles.
