A sphere has a radius of 3.5 inches.

Volume (to the nearest tenth) = cubic inches

The answer that I got was 179.6.

It is wrong ! i I miss a step?

V = (4/3) π r^3

= (4/3) π (3.5)^3 = 179.59438
which to the nearest tenth = 179.6

You are correct

For some reason the computer keeps saying my answer is wrong.

try 179.7 , obtained if 22/7 is used for an approximation of π.

I stand by my answer.

To calculate the volume of a sphere, you can use the formula:

Volume = (4/3) × π × r^3

In this formula, "r" represents the radius of the sphere. Let's substitute the given radius of 3.5 inches into the formula.

Volume = (4/3) × π × (3.5)^3

Now, let's evaluate the expression:

Volume = (4/3) × π × (42.875)

Volume = 179.59465148

When rounded to the nearest tenth, the volume of the sphere is approximately 179.6 cubic inches.

It seems that the answer you obtained, 179.6, is correct. If you have a different answer and believe it to be incorrect, please double-check your calculations to ensure accuracy.
