Q46 / 160 · AP EAMCET 2020 (17 Sep Shift 2) · Mathematics

The length of the diameter of the circle \(x^2+y^2-6 x-8 y=0\) is units

  • A
    5
  • Correct answer
    B
    10
  • C
    15
  • D
    20

Solution

Cirle is \(x^2+y^2-6 x-8 y=0\) Radius of circle is, \(r=\sqrt{g^2+f^2-c}=\sqrt{3^2+4^2-0}=5 \text { units }\) Diameter \(=2 r=10\) units

Hence, the correct answer is option: 'B'.
