The value represents a half-rotation in the radian angle system.
The POWER function is an alternative to theexponent operator(^).
Surface area of a cylinder
To calculate the surface area of a cylinder, you can use the standard geometric formula based on the PI function together with the exponent operator (^). In the example shown, the formula in D5, copied down, is: =2*PI()*B5*C5+2*PI()*B5^2 which returns the surface area of a cylinder with the radius given in column B and the height given in column C. Units are indicated generically with "u", and the resulting volume is units squared (u2).
