Answer:

6cm

Step-by-step explanation:

The below formula can be used to determine the volume of a cone;


V=\pi* r^2*(h)/(3)

Given V which is the volume of the cone as 602.88cm^3 and the height(h) as 16cm, let's go ahead and solve for radius(r) using the below steps;

Multiply both sides by 3;


3V=\pi* r^2* h

Divide both sides by the product of pi and h;


(3V)/(\pi h)=r^2

Take the square root of both sides;


r=\sqrt[]{(3V)/(\pi h)}

Substitute the given values and solve for r;


r=\sqrt[]{(3*602.88)/(3.14*16)}=\sqrt[]{(1808.64)/(50.24)}=6\operatorname{cm}
