All you need to do is multiply the diameter by pi. Pi's decimal equivalent is 3.14159... The reason that I put the triple period was to signify that pi is a non-ruccuring, or transcendental number, which means it has infinite digits after the decimal. For general purposes though all you would need to know is that pi = 3.14 since you would not likely need to calculate anything past two decimals.

What is the format to calculate the area of a diameter?
pi is a constant = 3.141592654 . . . . circle area = pi * ( ( diameter/2 )2 )
How do you calculate the diameter or radius of each circle?
Using the Circumference And Area.
How to calculate area of circle within a circle?
Take out the diameter of the outer circle from the distance between the two. Gives you the diameter of the inner circle then pi r squared it.
How do you calculate the area of a circle without a radius?
Use the diameter and divide it by two.
What is the area of a circle that has a 25 inch diameter?
Calculate the radius, which is simply 1/2 the diameter. Then use the standard formula for the area of a circle. ________________________________________________________________ The circle area = (pi) x diameter / 4 = 3.14 x 25/4 = 19.625 Sq inch
