Sandra calculated the height of a cylinder that has a volume of 576 pi cubic centimeters and a radius of 8 centimeters. Her work is shown below. V = B h Step 1: 576 pi = pi 8 squared h Step 2: 576 pi = 64 pi h Step 3: StartFraction 576 pi Over 64 pi EndFraction = StartFraction 64 pi Over 64 pi EndFraction h Step 4: h = 9 pi cm What error did Sandra make when calculating the height of the cylinder? In step 1, she substituted into the volume formula incorrectly. In step 2, she calculated 8 squared incorrectly. It should be 16 rather than 64. In step 4, the pi should have canceled, making the correct answer 9 cm. Sandra calculated the height of the cylinder correctly.

The error was made in step 4, should have also been cancelled making the correct answer as 9 cm.

Step-by-step explanation:

Given that:

Volume of cylinder,

Radius of cylinder, r = 8 cm

To find:

The error in calculating the height of cylinder by Sandra ?

Solution:

We know that volume of a cylinder is given as:

Where B is the area of circular base and

h is the height of cylinder.

Area of a circle is given as,

Let us put it in the formula of volume:

Step 1:

Putting the values of V and r:

So, it is correct.

Step 2:

Solving square of 8:

So, step 2 is also correct.

Step 3:

Step 4:

Cancelling 64 ,

h = 9 cm

So, the error was made in step 4, should have also been cancelled making the correct answer as 9 cm.
