pi is a constant = 3.141592654 . . . .
circle area = pi * ( ( diameter/2 )2 )
Divide the area by pi (= 3.14159 approx) to get diameter.
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.
Use the diameter and divide it by two.
Calculate the area of the ball with a diameter of 12 metres
Divide the area by pi (= 3.14159 approx) to get diameter.
Divide the area by Pi to get the diameter.
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
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.
4*pi*(d/2)2Where d is diameter
