Can some one please help me with this math question? Please and thank you

Answer:

$V = 6373.2cm^3$

Step-by-step explanation:

Given

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

$D = 23cm$ --- Diameter

Required

Find the volume

First, we calculate the radius, r

$r = \frac{1}{2}D$

Substitute 23 for D

$r = \frac{1}{2} * 23$

$r = 11.5$

Substitute 11.5 for r in $V = \frac{4}{3}\pi r^3$

$V = \frac{4}{3} * \frac{22}{7} * 11.5^3$

$V = \frac{4*22*11.5^3}{3*7}$

$V = \frac{133837}{21}$

$V = 6373.19047619$

$V = 6373.2cm^3$
