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...
pi squared = approximately 9.8696044
No because pi still remains as an irrational when squared.
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.
19.7392088 is also = to pi for instince infinaty=pi = never tnding so the formlea infinity=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!
pi radius squared. (radius squared, then multiply by pi.)
the same as pi squared, which is 9.86960440109
It is: 144*pi
pi times the radius squared pi r squared
Pi is the ratio of a circle's circumference to its radius and equals approx 3.14. Therefore pi squared is 3.14... x 3.14... = 9.8696.
SA=2(pi times r squared) + h(pi 2 r) or (easier way) 2 pi r squared + 2 pi r h
Pi r squared is the formula for the area of a circle. 2 pi r squared is twice that.
The same as pi squared, which is roughly 9.86960440109
the formula for a cylinder is pi *radius squared*height
The area of a circle = pi*r2
square root of x/pi
The area of a circle is pi x radius2. You know the radius already since it's diameter/2 which is 8 inches. Your answer then is pi times 8 inches squared which is 64 times pi inches squared. pi is about 3.1415 so multiply that by 64 if you need to resolve the pi.
that is 14,519.4 squared
the volume of a cylinder is (pi)r squared times the height, same as a circle but plus the height so the answer here would be ((pi) x 1) squared x 5. or 5 pi squared
The area of a circle is: pi times radius squared
Pi has many usages in mathematics some of which are:- Area of a circle = pi*radius squared Circumference of a circle = diameter*pi or 2*pi*radius Surface area of a sphere = 4*pi*radius squared Volume of a sphere = 4/3*pi*radius cubed Volume of a cone = 1/3*pi*radius squared*height The value of pi is found by dividing the circumference of a circle by its diameter
