Ahmed found the volume of a cone having both a height and a diameter of 6 centimeters. His work is shown below.

What was Ahmed's first error?

In Step 1, the radius should be found by multiplying the diameter by 2.

In Step 2, the formula 2pi r should be used to find the area of the circle.

In Step 3, the resulting area should be in terms of pi

In Step 4, the units of the resulting volume should be cm^2

Faith Little · Answer 2

Whenever we are given with the diameter of any such figure,

to find the radius, we divide the diameter by 2.

We know that

Diameter = 2 * radius

or

Radius = Diameter / 2

,

In the question it says the in first step that

the radius should be found by multiplying the diameter by 2

, this is the first error

It should be that

the radius should be found by dividing the diameter by 2
