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.

What is a spatial figure where in all the points are of the same distance from the center inside the sphere?
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.

What expression gives the volume of a sphere with radius 15?
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.

What is the surface area of a sphere with diameter 18 CM?
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!
