Question

The volume of a right circular cone is 45 cubic centimeters, and the radius of

Answer 1

Answer:

5cm

Step-by-step explanation:

Given parameters:

Volume = 45cm³

Radius  = 3cm

Unknown:

Height of the cone  = ?

Solution:

Volume of cone is given as ;

  V = $\frac{1}{3} \pi$ r² h

r is the radius

h is the height

      45  =  $\frac{1}{3} \pi$x 3² x h

      45  = 3π x h

       h  = $\frac{45}{3 x3.142}$   = 4.77cm

5cm is the closest answer choice
