it is pi..... wait no it isnt.....pi squared to the one half power is not pi...
This is the equation of a semi-circle, or a half circle.
(pi) R2 x 34 = 81 pi R2
area=pi r squared the r is the radius which is half of the diameter so area =pi mulitplied by 45 squared which is 6361.725124mm
The area of a full circle is pi x R squared where R = RADIUS The area of a semi circle is half of that, or pi x R squared/2
pi times the radius squared pi r squared
This is the equation of a semi-circle, or a half circle.
If working in radians, the cosine of one-quarter of pi is equal to the square root of 0.5. Squaring this gives 0.5, or exactly one-half.
(pi) R2 x 34 = 81 pi R2
area=pi r squared the r is the radius which is half of the diameter so area =pi mulitplied by 45 squared which is 6361.725124mm
The area of a full circle is pi x R squared where R = RADIUS The area of a semi circle is half of that, or pi x R squared/2
pi*r squared:2 *=multiply : =divide
pi squared = approximately 9.8696044
[pi^(1/3)]^2 * pi = pi^(2/3) * pi = pi^(5/3) The answer is the cubic root of pi to the fifth power.
pi squared is 9.869604401... pi cubed is 31.00627668
pi x 2.5 squared because 2.5 is the radius. the radius OS half the diameter. the formula for area of a circle is pi x r squared. pi is 3.141593
No because pi still remains as an irrational when squared.
The general formula for the area of a circle is pi times the radius squared. The radius is half the diameter, so the area is pi times half the diameter times half the diameter again.
