Karen ate a 70 degree section of her birthday pie with a diameter of 12 inches what is the are of the section

Step-by-step explanation:

First of all, we have to calculate the total area of the pie.

The area of a circle is given by:

where r is the radius of the circle.

Here, the diameter of the pie is 12 inches, so the radius is half of this value:

r = 6 in.

So the area of the pie is

Now we can solve this problem by using the rule of three.

In fact, we know that the total area of the pie corresponds to an angle of 360 degrees.

So, if we want to find the area corresponding to an angle of 70 degrees, we can write:

And substituting the value of the area A found above, we can find A', the area of the section of the pie:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
