Question about Homework

It sounds like you are trying to determine the surface area of a cylinder.

The area of the top and the bottom of the cylinder (which are circles) are pi x r ^ 2. Since there are two of them, we have to multiply this answer by 2.

The surface area of the side is going to be the circumference of the circle times the height. The circumference is 2 x pi x r and the height is 15 inches.

To get the total surface area, we have to add these amounts together.

Good luck,

Paul

I have no idea about your knowledge of calculus. But the solution requires calculus (I am in no mood to introduce a Delta V and Delta t and let Delta t approach zero.)

SOURCE: How many square inches in 31 1/8 x 15 3/4 inches

31.125 multiplied by 15.75 = 490.21875 square inches.

.21875 is the same as 7/32

So, final answer: 490 7/32" squared.

Just want to make sure that we are on the same page.

2^(-3) + 3^(-3)

2 to the exponent -3 + 3 to the exponent -3

Because of BEDMAS, we have to do the exponent calculations first and then do the addition between the two terms last.

The rule of negative exponents is you put 1 over the base to the same exponent, but change the exponent from negative to positive.

=1/(2^3) + 1/(3^3)

= 1/8 + 1/27

To add or subtract numbers, we need a common denominator.

Let's factor 8 and 27 to get the lowest common multiple.

8 - 1 2 4 8

27 - 1 3 9 27

Nothing in common to eliminate, so we have to use 8 x 27 or 216.

27/216 + 8/216 = 35/216

Good luck,

Paul

The hypotenuse length is 5.

That ratio is 3/4, height/base, in both triangles. Is that what you mean?

Ratios are normally expressed as a fraction, not a decimal.

I'm not sure this is correct, but it may give you some hints.

n = a/sqrt(m) and given the point (4,11)

Substituting the point (4,11), I get a = 22

So n = 22/sqrt(m)

Good luck,

Paul

2 feet 8 inches is is 32 inches.

4,500 x 32 is 144,000 inches

divide it by 12 to to bring it back to feet. The answer is 12,000.

When working in feet, which have 12 inches, it is easier to bring to a single figure rather than using fractions. This is the benefit of the Metric system as everything is based on 10s and hundreds and thousands. Millimeters, Centimeters and Metres.
