To find the total surface area of this sphere you need to apply this formula:


4*pi*r^2


diameter= 50 cm


The diameter is given so you divide by 2 in order to find the radius.


50/2=25


r=25


The radius is 25 cm


Then you plug in the radius in the formula.


4*pi*25^2


4x3.14=12.56


(25)2=625


(625)(12.56)=7850


The solution is 7850


ANS: 7850= TA
