High School Mathematics 4.12 Surface Area of a Sphere - II
Example:
Find the surface area of the sphere of diameter is 10.5 cm. Solution: Surface area of sphere = pi * d^{2} (this equation if we know diameter)
Given that,
d = 10.5 cm.
= 22/7 * 10.5 * 10.5
= 346.5 Sq. cm.
Directions: Solve the following problems. Also write at least 5 examples of your own.
