Answer:
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
