Find the surface area of a sphere with a diameter of 30 inches. leave your answer in terms of pi
2,826pi in squared
3,600pi in squared
225pi in squared
900pi in squared
To find the surface area of a sphere, we use the formula:
Surface Area = 4 * π * r^2
where r is the radius of the sphere. The diameter of the sphere is given as 30 inches, so the radius (r) will be half of the diameter, which is 30 / 2 = 15 inches.
Plugging the radius into the surface area formula:
Surface Area = 4 * π * (15 inches)^2
Surface Area = 4 * π * 225 inches^2
Surface Area = 900 * π inches^2
Therefore, the surface area of the sphere is 900π square inches. The correct answer from your options is:
900π in squared
