Ahmed found the volume of a cone having both a height and a diameter of 6 centimeters. His work is shown below.
Step 1
Find the radius.
6
radius = z = 3 cm
Step 2
Step 3
Find the area of the base.
Area of base = x(3)2 - 9 x cm
Multiply the area of the base by the height.
9xx 6 = 54 cm
Divide 54 by 3 to find the volume of the cone.
Volume of the cone =
54 - 18cm
Step 4
54
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 2 ar should be used to find the area of the circle.
