Find the area of the circle to the nearest tenth, if n=3.14 and a=5in.
a.78.5
b.69.4
c.31.5
d.47.5

For this case we have by definition that the area of the circle is given by:

We have as data that the radio is given by:

We use

So:

Option A

not solvable

step-by-step explanation:

we need more information, or at least an

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
