The surface area of this sphere is 1256 cm² Round to the nearest tenth.
What is the surface area of a sphere?
A sphere is a three-dimensional shape analouge of a circle.
The area of a sphere = 4πr^2
To calculate the area of a sphere. We have as data:
Radius (r) = 10cm
Pi(π) = 3.14
The formula to calculate the area of a sphere is:
S.A. = 4nr²
V = πr³
Substituting values into the equation.
S.A. = 4 (3.14) (10)²
S.A = 1256 cm²
Hence, the surface area of this sphere is 1256 cm² Round to the nearest tenth.
