What is the surface area of a sphere with radius r, of 9 cm? Use 3.14 for pie
(Type an integer or decimal rounded to the nearest hundredth as needed.)
The surface area of a sphere is given by the formula:
Surface Area = 4πr^2
Plugging in r = 9 cm and using the approximation of π = 3.14, we have:
Surface Area = 4 * 3.14 * (9)^2 = 1017.36
Therefore, the surface area of a sphere with radius 9 cm is approximately 1017.36 square centimeters.
