Answer : The radius of bowl is, 7.428 inches.
Step-by-step explanation :
As we are given that:
Depth of the bowl = D(r) = 0.145 r²
Given:
Depth of the bowl = D = 8 inches
Now put all the given values in the above expression, we get the radius of bowl.
[tex]D(r)=0.145\times r^2[/tex]
[tex]8\text{ inches}=0.145\times r^2[/tex]
[tex]r^2=\frac{8\text{ inches}}{0.145}[/tex]
[tex]r=\sqrt{\frac{8\text{ inches}}{0.145}}[/tex]
[tex]r=7.428\text{ inches}[/tex]
Therefore, the radius of bowl is, 7.428 inches.
