The volume of a sphere is 2,098 pi m^3 what is the surface area of the sphere to the nearest tenth?

Karo-lina-s [1.5K]

Answer:

3139.5 m²

Step-by-step explanation:

the formula for the volume of a sphere of radius r is V = (4/3)πr³. In this particular case, V = 2098π m³ = (4/3)πr³, and from this we can calculate the radius, r:

2098π m³

r³ = ----------------- = (3/4)(2098 = 1483/5

(4/3)π

Thus r = ∛1573.5 m³ = 11.64 m

Then the surface area is A = 4πr², which in this case is

A = 4(3.14159)(11.64 m)^2 = 1702.6 m² (which is to the nearest tenth).

Answer:

none of the above

Step-by-step explanation:

The problem as written cannot have any of the solutions offered.

For any of those choices, the right side expression will be irrational. The left side expression will be rational for any rational value of x, so cannot be equal to the right-side expression.

The solution is an irrational number near ...

x ≈ 1.33682898582
