Question

find the volume of the following figure using the appropriate formula. use $\frac{22}{7}$ for $pi$. sphere: $v = \frac{4}{3}pi r^{3}$

Explanation:

Step1: Identify the radius value

The radius $r = 1$ in.

Step2: Substitute values into formula

Substitute $r = 1$ and $\pi=\frac{22}{7}$ into $V=\frac{4}{3}\pi r^{3}$. So $V=\frac{4}{3}\times\frac{22}{7}\times1^{3}$.

Step3: Calculate the volume

$V=\frac{4\times22}{3\times7}=\frac{88}{21}\approx 4.19$ in³.

Answer:

$\frac{88}{21}$ in³ (or approximately $4.19$ in³)
