Total surface area of sphere of radius 3 cm is?

110 cm^2

113 cm^2

123 cm^2

116 cm^2

Given:

A sphere of radius 3 cm

Formula Used:

Total surface area of sphere = $4 \times 22/7 \times r^{2}$ ; where $r$ = radius of sphere

Calculation:

$\Rightarrow$ Total surface area of sphere = $4 \times 22/7 \times 3^{2}$

$\Rightarrow$ Total surface area of sphere = $\frac{792}{7} = 113.4 cm^{2} \approx 113 cm^{2}$

$∴$ required Total surface area of sphere = $113 cm^{2}$
