Given ⇒ Radius of the sphere, r=35 cm.We know, Surface area of the sphere is equal to 4πr2. So,A=4πr2=4×227×35×35=15400 cm2Therefore, option A is correct.

Find the surface area of the sphere whose radius is $35 cm$ .
$1540 {cm}^{2}$
$154 {cm}^{2}$
$15.400 {cm}^{2}$
$15400 {cm}^{2}$

Given $\Rightarrow$ Radius of the sphere, $r = 35 cm$ .

We know, Surface area of the sphere is equal to $4 π r^{2} .$ So,
$\begin{matrix} A & = 4 π r^{2} = 4 \times \frac{22}{7} \times 35 \times 35 = 15400 {cm}^{2} \end{matrix}$

Therefore, option $A$ is correct.
