Step-by-Step Solution
Distance between centres (15) > sum of radii (10), so the circles are separate, giving 4 common tangents.
Answer: D) 4
Two circles of radii 6 cm and 4 cm have their centres 15 cm apart.
Since 15 is greater than the sum of the radii (6 + 4 = 10), the circles lie completely apart.
How many common tangents can be drawn to them?
