Answer:
154 cm²
Step-by-step explanation:
Area of Sphere = 4πr²
r = 3.5 cm
Area = 4*(22/7)*3.5*3.5
=> 154 cm²

Explanation-:
Surface area of sphere -:
“SA = 4π r^2”
SA = Surface Area
π = 22/7 or 3.14
R = Radius

Given ,
Radius of a sphere -: 3.5 cm
To find,
Surface Area of sphere
______________________________
Formula of Surface Area -:
“SA = 4π r^2”
SA = Surface Area = ??
π = 22/7 or 3.14
R = Radius = 3.5 cm
= 4 x 22/7 x 3.5 x 3.5
= 4 x 3.14 x 3.5 x 3.5
= 12.56 x 12.5
= 153.86 cm^2
Hence ,
Surface Area of sphere -: 153.86 cm^2
_____________________________
Sphere -: A sphere is a geometrical
object in three-dimensional space that is
the surface of a ball.
