V = 4/3r3. A sphere has a radius of 4 inches.

Volume (to the nearest tenth) = cubic inches

The answer I got was 261.2 but it was wrong.

To find the volume of a sphere, we use the formula V = (4/3)πr^3, where V represents the volume and r represents the radius. We substitute the given radius into the formula and calculate:

V = (4/3)π(4)^3
V = (4/3)π(64)
V = (4/3)(3.14159)(64)
V ≈ 268.08315

Rounded to the nearest tenth, the volume of the sphere is approximately 268.1 cubic inches.

To find the volume of a sphere, you can use the formula V = (4/3)πr^3, where V represents the volume and r represents the radius.

Given that the radius of the sphere is 4 inches, we can substitute the value into the formula:

V = (4/3)π(4^3)
V = (4/3)π(64)
V = (4/3)π(64)
V = (4/3)(3.14)(64)
V = 268.08 cubic inches

Therefore, the volume of the sphere, rounded to the nearest tenth, is approximately 268.1 cubic inches, not 261.2.

This is the formula for the volume of a sphere.

V = (4/3) * pi * r^3

V = (4/3) * 3.14 * 4^3

V = (4/3) * 3.14 * 64

V = (4/3) * 200.96

V = 267.9 cubic inches
