If a numerator and/or denominator in a fraction is irrational, the entire fraction is irrational. Since pi is irrational, pi divided by two is also irrational.
(pi)(1/pi)=1.4396 ...
the same as pi squared, which is 9.86960440109
The square root of pi times pi is simply pi. Because pi*pi=pi squared, the squared and the square root will cancel each other, leaving just pi.
Pi to the 5th power is approximately 306.019684785
Entire surface area: (pi*radius^2)+(pi*radius*slant length)
To have an "entire approximation" in itself is an oxymoron. We have to approximate pi because you cannot express the true value of pi as a decimal. It goes on forever. This is an invalid question. Pi is generally approximated, however, as 22/7 or 3.14.
Entire surface area = (2*pi*radius2)+(pi*diameter*height)
Entire surface area of a cylinder = (2*pi*radius2)+(pi*diameter*height)
Entire surface area: (2*pi*121)+(22*pi*23) = = 748*pi square inches
Entire surface area of a cone: pi*radius^2 plus pi*radius*slant length
Volume in cubic units = pi*radius2*height Entire surface area in square units = (2*pi*radius2)+(pi*diameter*height)
Entire surface area: (2*pi*36)+(12*pi*15) = 252*pi square units
Entire surface area of a cone: pi*radius^2 plus pi*radius*slant length
Entire surface area of a cone: pi*radius^2 plus pi*radius*slant length
Entire surface area of a cylinder = (2*pi*radius2)+(pi*diameter*height)
Surface Area = 2(pi r 2) + (2 pi r)* h
