Question

If the volume of a sphere is equal to its
surface area, then the circumference of a
cross sectional circle whose centre
coincides with the sphere is:
$(1)2\pi \\(2)4\pi \\ (3)6\pi \\ (4)8\pi$
​

Answer 1

Answer:

0ption 3 is correct : 6 pi

$the \: volume \: of \: a \: sphere \: is \: equal \: to \: its \: </p><p>surface \: area, \\ \frac{4}{3} \pi \: {r}^{3} = 4\pi {r}^{2} \\ r \: = 3 \\ so \: circumference \: of \: circle \: = 2\pi \: r \\ = 2 \times \pi \: \times 3 \\ = 6\pi$
