Answer:
In Step 3, the resulting area should be in terms of π
Step-by-step explanation:
Area of the cone is [tex]\frac{1}{3} \pi r^{2} h[/tex]
[tex]= \frac{base area(height)}{3}[/tex]
To find the radius, we should divide the diameter by 2.
So, Ahmed's first step was perfect!
For step 2, we should find the base area [tex]\pi r^{2}[/tex]
Ahmed perfectly done this in step 2.
For the next step, we should multiply the base area with the height.
Ahmed did this in Step 3 but he forgot to write [tex]\pi[/tex] in the result.
