Question

25 points please help ASAP part 2

What is the volume of a cylinder with a height of 9 in. and a diameter of 8 in.? Use 3.14 to approximate π to calculate the approximate answer. Round the answer to a whole number.

Answer 1

The formula to find the volume of a cylinder is pi mulitplied by radius squared multiplied by height. You multiply 3.14×4 squared×9 which is 452.16 or 452. The answer is 452 inches cubed.

Answer 2

Hello from MrBillDoesMath!

Answer:

452

Discussion:

The volume of a cylinder of height "h" and radius "r" is given by the formula (Pi *r^2) * h. As the diameter of a circle is twice the radius, this formula is equivalent to

Volume = Pi * (d/2)^2 * h

= Pi * (8/2)^2 * 9

= Pi * 4^2 * 9

= Pi 16 * 9

= Pi * 144

Using the approximation 3.14 for Pi,

Volume = (3.14) * 144 = 452.2

The Question asks for an answer rounded to a whole number, so the answer becomes 452

Thank you,
