Divide the area by pi (= 3.14159 approx) to get diameter.
pi is a constant = 3.141592654 . . . . circle area = pi * ( ( diameter/2 )2 )
Diameter x Thickness
Using the Circumference And Area.
First calculate the radius (1/2 of the diameter), then use the formula area = pi x r2.
To calculate the area of a pipe (which is a cylindrical shape), you can use the formula for the cross-sectional area of a cylinder, ( A = \pi r^2 ), where ( r ) is the radius of the pipe. If you have the diameter, you can find the radius by dividing the diameter by 2. For a pipe with a specific outer diameter and thickness, you would use the inner radius to find the area of the flow section.
Calculate the area of the ball with a diameter of 12 metres
Divide the area by Pi to get the diameter.
pi is a constant = 3.141592654 . . . . circle area = pi * ( ( diameter/2 )2 )
You don't. You can calculate iits radius and cross-sectional area but its diameter has insufficient information to calculate its length
Diameter x Thickness
Area is 4.6 m2
Area= Pi r squared
If by "it" you mean a circle, once you know the diameter, you can calculate its radius, its circumference, and its area.
Using the Circumference And Area.
Area is 4.6 m2
First calculate the radius (1/2 of the diameter), then use the formula area = pi x r2.
if you have the diameter or the arc, then you can divide the diameter by two, or you can use the arc to calculate it.
