How many square feet of surface area is there on a spherical tank with a diameter of 4 foot?

Area of a sphere is 4 pi (radius)2
Radius = 1/2 diameter
Area of your tank = 4 pi (2)2 = 16 pi = 50.27square feet.
(Same area, in principle, inside the tank too.)

What is the surface area for softball with a diameter of 12?
The surface area of a softball with a diameter of 12 is about 452.4 square units.
When a spherical cell increases in diameter from 2um to 20 um by what factor does its surface area change?
The surface area will increase one hundred fold.
What is the surface area of a cylinder that has a diameter of 8 inches and a height of 5?
Total surface area is 226 square inches and the curved surface area is 126 square inches.
If the diameter of a spherical cell goes from 1 to 2 its surface are goes from 3 to?
If the diameter doubles (x 2), the surface area quadruples (x 4).So if the original surface area is 3 units, the new one will be 12 units.
What is the surface area of a cylinder with diameter 24ft and height 16ft?
The surface area of this cylinder is 2,111.15 square feet.
What is the relationship between the surface area and the volume of a cell as one increases or decreases so does the other?
Remember that as the diameter of a spherical cell increases, the surface area increases as the square of the diameter, and the volume increases as the cube of the diameter, so volume increases much faster than surface area. The same principle applies for other shapes than spherical cells, but the math is more complicated.
What is the surface area that has a diameter of 25 in?
The surface area of a sphere with a diameter of 25 inches is about 1,963.5 square inches.

What is the surface area if the diameter is 2.7 inches?
The surface area of a sphere with a diameter of 2.7 inches is about 23 square inches.
What is surface area of a circle that has a diameter of 14 in?
The surface area of a sphere with a diameter of 14 inches is about 615.8 square inches.
When a spherical cell increases in diameter from 2um to 20 um by what factor does its surface area change?
The surface area will increase one hundred fold.
What is the total surface area of a satellite that has a diameter of 60 cm?
Assuming the satellite is spherical, the radius is half the diameter, which is 30 cm. The surface area of a sphere is 4 pi times the radius squared. 4 * 3.14 * 30 ^ 2 = 12.56 * 900 = 11304 square cm
What is the surface area of a sphere with diameter 18 feet?
The surface area of a sphere with a diameter of 18 feet is: 1,020 square feet.
If you know the diameter of a sphere you can find its surface area?
Yes, that's true. The surface area is (the square of the diameter) multiplied by (pi).
How do you calculate the surface area of a spherical tank with a diameter of 96 inches?
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
What is the surface area of a sphere whose diameter is 18 feet?
The surface area is 1,020 square feet.
What is the surface area of a cylinder with height of 2 and diameter of 4 what is the surface area?
About 50.24 square units.
