The area of any sphere is (4 pi) times (Radius)2. It doesn't matter whether it's
a planet or a spherical bubble gum. You ought to be able to handle that.
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.
Calculate the area of the ball with a diameter of 12 metres
Surface area of the sphere = 4*pi*63502 = 506707479.1 square km
Divide the area by pi (= 3.14159 approx) to get diameter.
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
