The value represents a half-rotation in the radian angle system.
The POWER function is an alternative to theexponent operator(^).
Surface area of a cone
To calculate the surface area of a cone, you can use the PI function together with the exponent operator (^) and the SQRT function. In the example shown, the formula in D5, copied down, is: =1/3*PI()*B5^2*C5 The formula returns the surface area of a cone with radius given in column B and height given in column C. Units are indicated generically with "u", and the resulting area is units squared (u2).
