$\Large\fbox{\color{purple}{ SOLUTION }}$

$\Large\mathcal\red {SPHERE }$

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

$\Large\mathcal\pink{HEMISPHERE}$

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

Answer 2

Step-by-step explanation:

TOTAL SURFACE AREA OF SPHERE

$4\pi {r}^{2}$

TOTAL SURFACE AREA OF HEMISPHERE

$3\pi {r}^{2}$

LATERAL SURFACE AREA OF HEMISPHERE

$2\pi {r}^{2}$
