A lid has a diameter of 8 inches. What is the area of the lid?

1 answer:

4 0

Answer: Ok So If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14.

The formula for working out the circumference of a circle is:

Circumference of circle = π x Diameter of circle

This is typically written as C = πd. This tells us that the circumference of the circle is three “and a bit” times as long as the diameter."

Which is the value of the expression ((10^4)(5^2)/(10^3)(5^3))^3

Answer:

Step-by-step explanation:

Let's set this up to see if we can simplify it a bit:

$(\frac{10^4*5^2}{10^3*5^3})^3$

Notice we have 4 tens on top and 3 on bottom, so we can eliminate the bottom 3 altogether and leave just one on top. And we have 2 fives on the top and 3 on bottom, so we can eliminate the 2 on the top and leave one on the bottom. Now that looks like this:

$(\frac{10}{5})^3$

10 divided by 5 is 2, and 2 cubed is 8

Answer:

no there can be no such thing to lose legs or those 2 angles added up already are 180 degrees and the 180 has to be split up between 3 angles and if 2 of the angles were 90 degrees the other 2 angles also would be creating a square
