Find the surface area and volume for this sphere. The diameter is 42 inches.
To find the surface area of a sphere, you can use the formula:
Surface Area = 4πr^2
To find the volume of a sphere, you can use the formula:
Volume = (4/3)πr^3
Given that the diameter of the sphere is 42 inches, the radius (r) would be half of the diameter, which is 21 inches.
Surface Area = 4π(21)^2
Surface Area = 4 x 3.14 x 441
Surface Area = 5541.84 square inches
Volume = (4/3)π(21)^3
Volume = (4/3) x 3.14 x 9261
Volume = 39,097.68 cubic inches
Therefore, the surface area of the sphere is 5541.84 square inches and the volume of the sphere is 39,097.68 cubic inches.
