konstantin123 [22]

Answer : 4 cm

Step-by-step explanation:

Hi, the radius of a cone is the radius of its circular base.

Since we know the diameter value (8 centimeters) we have ot apply the next formula:

Diameter = radius x 2

Replacing with the values given

8 = 2r

Solving for r:

8/2=r

4=r

So, the radius of the cone is 4 centimeters.
