What is the measure of the radius of the cone in the diagram below? A cone has a height of 6 centimeters and diameter of 8 centimeters. 3 cm 4 cm 6 cm 8 cm

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.

Feel free to ask for more if needed or if you did not understand something.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
