Question

Which of the following is the best approximation of the volume of a sphere with a 7 cm radius?

Answer 1

To find the volume of a sphere you would use the equation: $\frac{4}{3}$πr³

You would plug in the radius in r

Your equation would look like this now:

$\frac{4}{3}$π(7)³

When you solve that you would get:

1436

Since it's 3 dimentional you would use ⇒ ³

Your answer would be B. 1436cm³

Answer 2

the answer is 1436.03 but your approximation is 1436
