“There comes a time in a person's life when they realize something is missing...and often times, they come to realize that it is because they do not know how to calculate the surface area of a sphere!”- Victus_Maestro

Area of Circle

Area of Circle = Area of rectangle = Base x height

Height Area of Circle = Area of rectangle = base x heightradius Base = one-half circumference Area of Circle= Area of rectangle

Surface Area Rectangular Solid Cylinder Cone Pyramid Surface area: total area of the surface of a 3D object, measured in square units.

Surface Area of Sphere
