The volume of a sphere whose radius is 9 meters is: 3,054 meters3
(4/3)*pi The formula for the volume of a sphere is (4/3)*pi*radius3
V = 268.1 cubic feet.
V = 4/3*pi*r^3 you do the math
In order to find the surface area we must first find the radius of the sphere:- Volume of the sphere = 4/3*pi*radius3 = 113.1 cubic inches Multiply both sides by 3: 4*pi*radius3 = 339.3 Divide both sides by 4*pi: radius3 = 27.0006361 Cube root both sides: radius = 3.000033559 Surface area of the sphere = 4*pi*3.0000235592 = 113.0991118 square inches
