Question

formulas of sphere.
first answer brainliest.

Answer 1

CSA/TSA=4 pi r²

VOLUME =4/3 pi r cube.

Answer 2

***BONJOUR**

^_^

"Good question".

Here is probably the perfect answer..

Volume of sphere - 4/3 pi r^3

Surface area of sphere - 4pi r ^2

(spherical shell / hollow sphere)-

Surface area - 4pi R^2

volume - 4/3 pi (R^3 - r^3)

Hope helped ! ^_^
