The area of the circle whose centre is at (1, 2) and which passes through the point (4, 6) is Options: A . &nbsp 5 π B . &nbsp 10 π C . &nbsp 25 π D . &nbsp None of these

Answer: Option C : C Radius = √ ( 1 – 4 ) 2 + ( 2 − 6 ) 2 = 5 Hence the area is given by π r 2 = 25 π sq. units.

Question -

The area of the circle whose centre is at (1, 2) and which passes through the point (4, 6) is

Options:

A .

5 π

B .

10 π

C .

25 π

D . None of these

Answer: Option C
:
C
Radius =

\sqrt{(1 - 4)^{2} + (2 - 6)^{2}} = 5

Hence the area is given by

π r^{2} = 25 π

sq. units.
