Question

find the total surface area of a hemisphere of radius 10cm {π=3.14
​

Answer 1

$\LARGE\star\mathfrak{\underline{\underline{\red{answer: }}}}$

$\large \mathtt{ \: radius \: = 10 \: cm} \\ \\\large \mathtt{tsa \: of \: hemisphere \: = 3\pi \: r {}^{2} } \\ \large \mathtt{= 3(3.14)(10) {}^{2} } \\ \large\mathtt{ = 3 \times 3.14 \times 100} \\\large \mathtt{ = \underline{\underline{942 \: cm {}^{2} }}}$
