The area of a circular surface uses the formula pi*the radius squared.
So for your question the radius is half the diameter or 4 feet
Pi is basically 3.14
3.14*4*4=50.24 square feet.
The depth of the water does not apply
But if your looking for the volumn
you multiply the area*depth or 50.24*1.5 = 75.36 cu.ft.
To calculate the number of gallons multiply volumn*7.48 = 563.73 gal.

∙ 16y agoA flat round object is a circle. Surface area of a circle = pi*radius squared.
You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2

To calculate the surface area of a pipe fitting, you need to use the formula 3.14 x L x D. The L stands for the length of the pipe and the D is the diameter of the pipe.
Calculate the area of the ball with a diameter of 12 metres
Divide the area by pi (= 3.14159 approx) to get diameter.
The surface area of a sphere with a diameter of 7cm is 153.9cm2
Generally, the heat transfer area of reference is considered to be the outside surface area of the tube. Therefore, figure the outside diameter of the tube to get the heat transfer area.
The surface area of a sphere with a diameter of 25 inches is about 1,963.5 square inches.
