Answer:
r=3.399
Step-by-step explanation:
82.3=1/2(4/3pir^3)
164.6=4/3pir^3
164.6*(3/4) = 123.45=pir^3
123.45/pi=39.2953554494=r^3
cube root of 39.2953554494 =3.399
r= around3.4
Hi there!
To find the amount of money needed for one class, we need to plug 1 into the equation as x, since x represents the amount of classes.
