Please help me with this question. refer to the image first. 5. The diagram below shows three circles. Circle A has a radius of 2 cm and circle B has a
radius of 1 cm.

PQ is a common tangent and all circles touch one another. Find the radius of the smallest
circle. PL5

The radius of the small circle is about 0.85 cm - 0.95 cm

Explanation: I am not completely sure but I drew the same figure with the same lengths as given and between both circles there is almost a gam of 2.5 - 3 cm and when we draw a circle between them the diameter is about 1.7 - 1.9 so dividing the diameter by 2 to get the radius we get 0.85 cm - 0.95 cm.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
