Answer to Question #268899 in Geometry for alex

Question

The volume of a cone shaped hole is 16 on ft cubes if the hole is 3 feet deep is hat is the radius of the hole?

Answer 1

Volume =B.A*height =1/3$\Pi$r² h

Thus Volume =16ft³ and Height= 3ft

Replacing in the equation

16=1/3$\Pi$r² 3

Reducing the numbers by canceling 1/3 with 3

so it will be:

16 = Πr²

r²=16/Π =16/3.14

taking square roots of both sides

Therefore, radius = 2.25676
