$\Large\mathcal\red {SPHERE }$

$\implies \: tsa \: = 4\pi \: {r}^{2} \\ \\ \implies \: csa \: = 4\pi \: {r}^{2} \\ \\ \implies \: volume \: = \frac{4}{3} \: {r}^{3}$

$\Large\mathcal\pink{HEMISPHERE}$

$\implies \: tsa \: =3\pi \: {r}^{2} \\ \\ \implies \: csa \: = 2\pi \: {r}^{2} \\ \\ \implies \: volume \: = \frac{2}{3} \pi \: {r}^{3}$

$\huge\underline\pink{Answer}$

➡️✨✨formula of hemisphere :-

Volume of a hemisphere: V = (2/3)πr. ...

Circumference of the base of a hemisphere: C = 2πr.

Curved surface area of a hemisphere (1 side, external only): A = 2πr. ...

Calculate the base surface area of a hemisphere (a circle): B = πr. ... ✨✨

➡️✨✨formula of sphere :-

The formula for the volume of a sphere is V = 4/3 πr³. ✨✨
