Question

Find the volume of this sphere. Use 3.14 for pi and round your answer to the nearest 10th.

Answer 1

We have been image of a sphere. We are asked to find the volume of our given sphere.

We will use volume of sphere formula to solve our given problem.

$V=\frac{4}{3}\pi r^3$, where r represents radius of the sphere.

We can see that the radius of our given sphere is 10 cm.

$V=\frac{4}{3}\cdot 3.14\cdot (\text{10 cm})^3$

$V=\frac{4}{3}\cdot 3.14\cdot 1000\text{ cm}^3$

$V=\frac{4}{3}\cdot 3140\text{ cm}^3$

$V=4186.6666\text{ cm}^3$

Upon rounding to nearest tenth, we will get:

$V\approx 4186.7\text{ cm}^3$

Therefore, the volume of the given sphere is approximately $4186.7\text{ cm}^3$ and last option is the correct choice.

Answer 2

Answer:

Approximately 4th answer is correct.

Step-by-step explanation:

$V= \frac{4}{3} π {r}^{3} \\ = \frac{4}{3} ·π· {10}^{3} \\ ≈4188.7902$
