Surface area of a sphere: 4*pi*r^2
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.
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

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.
Volume: 4/3*pi*radius3 = 140 By making the radius the subject of the above gives it a value of 3.221166265 cm Surface area: 4*pi*3.2211662652 = 130.387557 square cm

4/3*Pi*163 = 17,157.28 cubic units
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!
