Answer:

1.75 cm

Step-by-step explanation:

The volume of a cone is 238  with height 74. To find the radius, substitute and solve for r.

[tex][tex]V= \frac{1}{3}\pi r^2 h\\ 238= \frac{1}{3} \pi (r^2)(74) \\ 238*3= \pi (r^2)(74)\\ \frac{714}{74\pi} = r^2\\\sqrt{\frac{714}{232.36} } =r\\ 1.75=r[/tex][/tex].
