A sphere is a 3D figure that is circular in shape, e.g., a ball. All points on the sphere are equidistant from a single point inside the sphere called the centre. Surface Area = 4πr2 Volume = (4/3)πr3 Theory –Surface Area and Volume of a Sphere
Find the volume and surface area of a sphere with radius 12 cm. Surface Area = 4πr2 Volume = (4/3)πr3 Example 1
Find the volume of a volleyball if its circumference is 26". Surface Area = 4πr2 Volume = (4/3)πr3 Example 2
Find the volume and surface area of a storage tank if a cylinder is capped at both ends by half spheres as shown: Surface Area of a Sphere = 4πr2 Volume of a Sphere = (4/3)πr3 Example 3
