In the same way, the average of outcome when you throw a $6$-sided die is $(1+2+3+4+5+6)/6=7/2$, which is not the value of any face on the die.This average value is certainly real.

WebFeb 1, 2024 · which does NOT describe a semicircle. I assume that the correct equation is: y = sqrt(25 - x^2) which would describe a semi-circle with a radius of 5. First, determine the mass and centroid of the square and the semicircle. For the square, the centroid is the exact center of the square and the mass is the area. So WebAnswer (1 of 3): Angles expressed in radians are actually dimensionless. To say that a circle has a circumference of 2\pi radians or just 2\pi, are the same thing, because the …
