Use this formula: 4 x pi x radius2
you do stuff
Well, the formula for the surface area for one sphere is 4∏r2So if you have two identical spheres, the formula for the surface area of both would be 8∏r2
To find the surface area of a shape, you need to calculate the total area of all its surfaces. This can be done by using the appropriate formulas for different shapes, such as rectangles, triangles, circles, and spheres. Add up the areas of all the surfaces to find the total surface area of the shape.
Two spheres that are congruent are the same size and shape. Therefore, they would have the same surface area. So this statement is always true.
The relationship between the surface areas of cylinders, cones, and spheres is that the surface area of a cylinder is equal to the sum of the areas of its two circular bases and its curved surface area, the surface area of a cone is equal to the sum of the area of its circular base and its curved surface area, and the surface area of a sphere is equal to four times the area of its circular base.
pi r squared.
A sphere has no base, and since it has no base, it has only a surface area and no lateral area.
The formula for the surface area of a sphere is 4πr2. The formula for the volume of a sphere is 4/3πr3.
Basic definition: "A point has no magnitude"
If you increase the radius, the volume will increase more than the area.
well at the bottom there is proberly two round spheres so what you do is you is times the spheres by the area of the pyramids base to find out how big it is. ^^this guy is trolling where is there a sphere in a pyramid
to find the surface area you have to first find the area of each part then add the areas together.
