☑️Here is your answer :-------

◼️As we know the formula for determining the area of sphere is =====> $4 \: \pi \: r {}^{2}$
Radius is given,
_______r =112cm_______

◼️Now, put the value of "r" in this formula:------
= $4 \: \times \: 3.14 \: \times \: 112 \: {}^{2}$
= $157552.64$$cm{}^{2}$

☑️Thus, this is the area of sphere. And total significant number is 8.

Hope it will help you!
Thanks!!☺️
