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.
A 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
82.466
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
A flat round object is a circle. Surface area of a circle = pi*radius squared.
4*pi*(d/2)2Where d is diameter
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
82.466
Surface area of the sphere = 4*pi*63502 = 506707479.1 square km
Calculate the area of the ball with a diameter of 12 metres
725.466
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
The formula to calculate the surface area of a 90-degree elbow is A = πDL, where A is the surface area, D is the diameter of the elbow, and L is the centerline radius. The surface area of the elbow is essentially the curved surface area of the elbow pipe fitting. This formula is derived from the mathematical principles of geometry and calculus, specifically the surface area of a cylinder.
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.
