Surface Area = S
S = 4*π*r^2
100π = 4*π*r^2
(100π) / (4π) = r^2
25 = r^2
r = 5
a radius of five
The surface area of a sphere is 4 PI r ^ 2.
So 4 PI r ^ 2 = 100 PI
r ^ 2 = 25
r = 5 cm
S = 4*pi*R^2 = 100pi*cm^2
>>>4*pi*r^2 = 100pi
>>4R^2 = 100
R^2 = 100/4=25
R=sqrt(25)= ***5cm***
SA = 4πr²
-------------
Plug in what you know:
100π = 4πr²
Divide both sides by 4π:
r² = 25
Square root both sides (radius can only be positive):
