Question

Centre of the circle Q is on the Y-axis. And the circle passes through the points (0, 7) and (0, −1). Circle intersects the positive X-axis at (P, 0). What is the value of ‘P’.

Answer 1

In the attachments I have answered this problem.   Equation of the required circle is found by using the given conditions.   Finally the value of P is found from the circle equation.   See the attachment for detailed solution

Answer 2

Answer:

Step-by-step explanation:Let the lengths and breadth of rectangle be l & b respectively.

Now l = b+5, perimeter = 2(l+b) = 58 cm

2(b +b +5) = 58

2b + 5 = 29

2b = 24

b = 12 and length = b +5 = 17
