The volume of a sphere is 3,500 pi m cubed. What is the surface area of the sphere to the nearest square meter?

Respuesta :

Answer:

[tex]2390 {m}^{2} [/tex]

Step-by-step explanation:

The formula for calculating the volume of a cylinder is

[tex]V = \frac{4}{3} \pi {r}^{3} [/tex]

It was given that the volume is 3,500π m³

We equate the formula to this value to get:

[tex]\frac{4}{3} \pi {r}^{3} = 3500\pi[/tex]

[tex] {r}^{3} = \frac{3 \times 3500\pi}{4\pi} [/tex]

[tex] {r}^{3} = 2625[/tex]

[tex]r = \sqrt[3]{2625} [/tex]

[tex]r = 13.79[/tex]

The area of a sphere is given by:

[tex] Area=4 \pi{r}^{2} [/tex]

[tex]Area=4 \times \pi \times {13.79}^{2} [/tex]

[tex]Area=2389.67[/tex]

Therefore the area is approximately 2390m² to the nearest square unit.
