Two circles are externally tangent. Lines PAB and PA'B' are common tangents with A and A' on the smaller circle and B' and B' on the larger circle. If `PA = AB = 4`, then area of the smaller circle, is

Two circles are externally tangent.Lines PAB and PA'B' are common tangents with A and A' on the smaller circle B and B' on the larger circle.If PA=AB=4, then find the radius of smaller circle

Two circle are externally tangent. Lines PAB and P A 'B ' are common tangents with A and A ' on the smaller circle and B and B ' on the larger circle. If PA=AB=4, then the square of the radius of the circle is___________

Two circle are externally tangent.Lines PAB and PA'B' are common tangents with A and A' on the smaller circle and B' and B' the on the larger circler circle and B=4 then the square of the radius of the circle is

Two circle are externally tangent. Lines P A B and P A ' B ' are common tangents with Aa n dA ' on the smaller circle and B^(prime)a n dB ' the on the larger circle. If P A=A B=4, then the square of the radius of the circle is___________

If two circle touch externally, then the number of their common tangents will be

Two circles touch each other externally at point P.A common tangent AB is drawn touching the circles at A and B.Find /_APB .

Two circles touch externally at P. A direct common tangent AB to two circles touch the circles at A and B. Then the measure of angleAPB is

The adjoining figure shows two circles with the same centre. The radius of the larger circle is 10 cm and the radius of the smaller circle is 4 cm(a) the area of the larger circle (b) the area of the smaller circle (c) the shaded area between the two circles. ( pi = 3.14)
