pi radius squared. (radius squared, then multiply by pi.)
n squared x n = n cubed but that does not equal 21. ---------------------------------------------------------------- Here is the correct version: We are looking for Pi squared times Pi which is Pi cubed Now Pi can never be written out exactly because its decimal number goes on for ever. However we can take a good approximation to Pi as 3.142 So Pi cubed = 3.142 x 3.142 x 3.142 = 31.018339 = 31.02 to 4 places.
The same as pi squared, which is roughly 9.86960440109
The area of a circle = pi*r2
pi*r squared*h pi*5 squared*12 pi*25*12 942!
pi squared is 9.869604401... pi cubed is 31.00627668
it is pi..... wait no it isnt.....pi squared to the one half power is not pi...
No because pi still remains as an irrational when squared.
19.7392088 is also = to pi for instince infinaty=pi = never tnding so the formlea infinity=pi.
pi times the radius squared pi r squared
It is: 144*pi
pi radius squared. (radius squared, then multiply by pi.)
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.
if you mean PI squared + PI squared / by 2 then that is.... 4.9298 solved on paper ... BUT if you mean what you said, the answer is YUMMY!
The surface area of a (closed) cylinder equals the surface area of both bases (the top and bottom), i.e. pi x radius squared (first base) + pi x radius squared (second base), plus the lateral surface area (the surface area of the curved side), i.e. circumference (pi x diameter) x height. Inserting the numbers: SA = pi x (2 m.) squared + pi x (2 m.) squared + pi x 4 m. x 6 m. = pi x 4 m. squared + pi x 4 m. squared + pi x 24 m. squared = 8 x pi m. squared + 24 x pi m. squared = 32 x pi meters squared.
Square root of Pi is about 1.772
n squared x n = n cubed but that does not equal 21. ---------------------------------------------------------------- Here is the correct version: We are looking for Pi squared times Pi which is Pi cubed Now Pi can never be written out exactly because its decimal number goes on for ever.
