James calculated the height of a cylinder that has a volume of 324

below.
cubic inches and a radius of 12 inches. His work is shown

V=Bn
Step 1: 3245 - 12h
Step 2: 324 = 24 sh
324 24
Step 3: 245 245
Step 4: h-13.5
inches

What is the first error that James made when calculating the height of the cylinder?

In step 1, he substituted into the volume formula incorrectly.
In step 2, he calculated 122 incorrectly. It should be 144 rather than 24.
In step 4, the should have canceled, making the correct answer 13.5 cm.

Answer:

In step 1, he substituted into the volume formula incorrectly.

Explanation:

James calculated the height of a cylinder that has a volume of 324 cubic inches.

radius = 12 inches.

The formula for volume is =
\pi r^(2) h

So, James calculated wrongly by using the wrong formula.

The step 1 is wrong.
