Correct option is B- -616 cm-2-We know-160-Surface area of sphere- -A- 4 -pi r-2- where -r- is the radius of sphere-Here- -r-7- cm -160-Therefore- -A-4-times -dfrac-22- 7 -times 7 -times 7-616- cm-2-Hence- option -B- is correct-

The surface area of a sphere of radius $$7$$ cm is:

Correct option is B. $$616 cm^2$$
We know,
Surface area of sphere, $$A= 4 \pi r^2$$, where $$r$$ is the radius of sphere.
Here, $$r=7\ cm $$
Therefore, $$A=4\times \dfrac{22} 7 \times 7 \times 7=616\ cm^2$$.
Hence, option $$B$$ is correct.
