The approximate surface area of a sphere can be found by sis nivel
evaluating the expression 4.22. r² for a given radius, r. What is the
approximate surface area, in square centimeters, of a sphere with a
radius of 7 centimeters?

Answer 1

The surface area of a sphere is found by SA = 4π(r2) = 4π(22) = 16π. ... surface area of solid sphere = 4πr2, where r is the length of the radius
