How do you calculate the area of a pizza crust?

To calculate the the area of a crust, we first need to find the whole area of the pizza.

Let's assume the entire radius is x. So our whole pizza area is π.

Then we find the radius of the "cheese" part of the pizza.

Let's assume the radius for this is y. So our area is π.

So we subtract both areas.

π-π.

And that's the basic gist of it.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
