# Find the Surface Area sphere (3.5)

r=3.5
The surface area of a sphere is equal to 4 times Pi π times the radius squared.
Substitute the value of the radius r=3.5 into the formula to find the surface area of the sphere. Pi π is approximately equal to 3.14.
4⋅π⋅3.52
Raise 3.5 to the power of 2.
4π⋅12.25
Multiply 4π⋅12.25.
Multiply 12.25 by 4.
49π
Multiply 49 by π.
