Surface area of a sphere: SA = 4πr2
The formula for calculating the surface charge density of a sphere is: Q / 4r, where represents the surface charge density, Q is the total charge on the sphere, and r is the radius of the sphere.
The surface area of a sphere with a radius of 2 is about 50.27 units2
The surface area of a sphere with a radius of 4.75 is about 283.5 units2
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
The surface of a sphere is: A=4? r2 From this, the surface are changes as the square of the radius. It does not change linearly.
The surface area of a sphere with a radius of 5m is 314.2m2
Formula for calculating the area of sphere is : 4 * pi * r * r
The surface area of a sphere that has a radius of 10 is: 1,260 square units.
The surface area of a sphere with radius 6 is: 452 square units.
The surface area of the sphere with the radius doubled is 200 units2.---> Confirmed
Finding the radius of a Sphere by using the surface area is a multi-step mathematical equation. The radius (r) of a sphere with a surface area of 1742400ft is 372.365ft.
The surface area ( A ) of a sphere with radius ( r ) is given by the expression ( A = 4\pi r^2 ). This formula calculates the total area that covers the surface of the sphere. The constant ( \pi ) (pi) is approximately 3.14159, and it represents the ratio of the circumference of a circle to its diameter.
