Question

A sphere of radius 13 cm is cut by a plane whose distance from the centre of the sphere is 5cm. What is the circumference of the section so obtained?

Options:

A . 10π

B . 12π

C . 24π

D . 26π

Answer: Option C
:
C

From the fig:X =

\sqrt{13^{2} - 5^{2}}

= 12x Thus, circumference= 24
