Question

What is the volume of the sphere?

Answer 1

Answer: 113.1

Step-by-step explanation:

The formula is $\frac{4}{3}$$\pi$$r^{3}$

The radius is 3, and 3 cubed is 27.

Then, 27 x $\pi$ is about 84.82

Finally, 84.82 x $\frac{4}{3}$ is about 113.1

Answer 2

Answer:

$36\pi ft^3$

Step-by-step explanation:

Remember the equation for the sphere is...

$V=\frac{4}{3} \pi r^3$

First step: $\frac{4}{3} \pi (3)^3$

Second step: $\frac{4}{3} \pi (27^3)$

Third step: Don't do 27 times 3 first. Make sure to cross out the dominator of 4/3, which is 3, and the 27.

Fourth step: Change the 27 to 9.

Fifth step: Multiply 4 times 9, which is 36.

Sixth step: Final answer is $36\pi ft^3$

Hope this helps and stay safe during these crucial times. We'll get through this!
