If the length of this piece of pie is 5 inches , what was the area of the whole pie

78.5in

Step-by-step explanation:

A=3.14(5^2)

A=3.14•25

A=78.5in

A = 78.54

Step-by-step explanation:

Thats an interesting way to ask this question... It got me at first lol

The length of the slice of pie should be the length of the radius.

If you know the radius of a circle, then you know enough to find the area.

You need to use a formula.

The formula is: A=πr^2

(^2 means squared)

variables:

A = area

r = radius

You do not know the area, so this is the variable you are solving for.

You DO know the radius(its 5), so replace the r in the equation formula with the value of r

It should look like:

A=π(5)^2

simplified, it should look like:

A=78.54

26?

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
