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.
Surface area of a sphere: 4*pi*r^2
Diameter: 41/pi = 13 inches rounded to a whole number Radius: 13/2 = 6.5 inches Surface area of the sphere: 4*pi*6.5 squared = 530.929 square inches to three decimal places
The surface area of the Earth can be calculated using the formula for the surface area of a sphere, which is (4\pi r^2), where (r) is the radius. The average radius of the Earth is approximately 6,371 kilometers. Plugging this value into the formula gives a total surface area of about 510.1 million square kilometers.

A spatial figure where all points are the same distance from the center is called a sphere. In a sphere, every point on its surface is equidistant from the center point, which defines its radius. This property gives the sphere its perfect symmetry and uniformity in all directions.
Surface area of a sphere: 4*pi*r^2
Area = 4*pi*r^2
4/3*Pi*163 = 17,157.28 cubic units
V = 4/3(PI*73) ≅ 1,436.76 units3

V = 4/3(Pi*r3): A sphere with a radius of 16 units has a volume of ≅17,157.28 cubic units.
If you mean 4*pi*r^2 then it is the formula for finding the surface area of a sphere
Volume = 4/3*pi*radius3 = 900 cubic inches By making the radius the subject of the above equation gives the sphere a radius of 5.989418137 inches. Surface area = 4*pi*5.9894181372 = 450.7950449 square inches
Volume in cubic units = 4/3*pi*153
The volume ( V ) of a sphere can be calculated using the formula ( V = \frac{4}{3} \pi r^3 ), where ( r ) is the radius. For a sphere with a radius of 15, the expression for its volume would be ( V = \frac{4}{3} \pi (15)^3 ). This simplifies to ( V = \frac{4}{3} \pi (3375) ), or ( V = 4500 \pi ) cubic units.

Oh, dude, you just need to find the radius first, which is half of the diameter, so that's 9 cm. Then you use the formula for the surface area of a sphere, which is 4πr^2. Plug in 9 for r, square it, multiply by 4, and then multiply by π. That gives you a surface area of 1017π square cm, or about 3190 square cm. Easy peasy!
