The volume of a cone-shaped hole is 1471 ft. If the hole is 9 ft deep, what is the radius of the hole



Please don’t put random numbers i just want the answer, I’ll make you brainliest

Answer :

jackiezhang2007

The volume πr^2*height/3=1471

π*r^2=1471/9*3

π*r^2=490.33(I'm rounding all my numbers to the hundredths digit)

r^2=490.33/3.14(taking 3.14 for pi)=about 156.16

r= sqrt 156.16=about 12.5

Again this answer is not precise but I rounded everything to the hundredths digit because pi is never ending. I hope it helped!
