Answers
GPT 3.5
To find the volume of a sphere, we can use the formula:
V = (4/3)πr^3
Given that the surface area is 482.8 mm², we can find the radius using the formula:
A = 4πr^2
Rearranging the equation, we get:
r^2 = A / (4π)
r^2 = 482.8 / (4π)
r^2 ≈ 38.48
Taking the square root of both sides, we find:
r ≈ √38.48
r ≈ 6.21 mm
Now we can substitute the value of 'r' into the volume formula:
V ≈ (4/3)π(6.21)^3
V ≈ 524.81 mm³
Therefore, the approximate volume of the sphere is 524.81 mm³.

Apologies for the incorrect response. Let's calculate the approximate volume of the sphere correctly.
Given that the surface area is 482.8 mm², we can find the radius using the formula:
A = 4πr²
Rearranging the equation, we have:
r² = A / (4π)
r² = 482.8 / (4π)
r² ≈ 38.48
Taking the square root of both sides, we find:
r ≈ √38.48
r ≈ 6.21 mm
Now, let's calculate the volume using the updated radius:
V = (4/3)πr³
V ≈ (4/3)π(6.21)³
V ≈ (4/3)π(6.21)(6.21)(6.21)
V ≈ (4/3)π(149.22)
V ≈ 198.74π
Using an approximation of π as 3.14, we can calculate the approximate volume:
V ≈ 198.74 * 3.14
V ≈ 624.67 mm³
Therefore, the approximate volume of the sphere is 624.67 mm³.
