Answer:
In Step 3, the resulting area should be in terms of pi.
Step-by-step explanation:
The question here involves a cone shape. The volume of a cone can be calculated using the formula: 1/3 πr^2h
According to the question, the diameter (d) and height (h) are 6cm respectively. Ahmed calculated the volume of this cone but made an error in step 3. Using the same way Ahmed solved it, the correct step by step calculation is as follows:
Step 1: Find the radius
Radius (r) = diameter/2
= 6/2 = 3cm
Step 2: Find the area of the base.
The base of a cone is a circle. The area of a circle is calculated using, πr^2 where r is radius and π is pie
Hence, Area of base = π × 3^2
Area = π × 3 × 3
Area = 9π centimeter square (cm^2)
Step 3: Multiply the area of the base by the height.
Area of base = 9π cm^2, height of cone = 6cm
Hence, we have; 9π × 6
= 54π centimeters cube (cm^3).
Step 4: Divide 54π by 3 to find the volume of the cone.
That is, 54π ÷ 3 = 18π
Hence, the volume of the cone is 18π centimeters cube (cm^3).
Therefore, Ahmed's first error was in step 3 where he failed to express 54 in terms of pie(π).
Answer:
Step 3 was is error
