Question

Area of the circle centre at
(2, 4) and passing through (4,6) is_____.

(A) 5π
(B) 10π
(C) 25π
(D) 100π​

Answer 1

Step-by-step explanation:

The centre of the circle is (2,4).

(x−2) ² +(y−4) ²=a²

It passes through (4,6).

Therefore, (4−2)²+(6−4)²=a²

⇒a²=4 + 4

⇒a=2√2

Thus radius a=2√2

Hence, area of circle is πr²

=π(2√2)²

=π8

The question is wrongly printed according to me .
