Radius 30cm

Area of sphere 4pir^2

area=11309.7 cm square

Answer 2

$\large \underline{ \underline{ \bold{ \: Answer : \: \: }}}$

$\to$ TSA of sphere = 1.1304 m²

$\large \underline{ \underline{ \bold{ \: Explanation : \: \: }}}$

$\to$ Radius = 30 cm = 0.3 m

$\large \fbox{ \fbox{ \bold{ TSA \: of \: sphere = 4\pi {(r)}^{2} }}}$

$\to$ TSA of sphere = 4 × 3.14 × ( 0.3 ) × ( 0.3 )

$\to$ TSA of sphere = 1.1304 m²
