i cant get his question can some please help me out with it......the area of a circle can be found by multiplying the number PIE times the square of a radius. If the radius of the circle is R, wrie an expression that represents the area of the circle?

Pi not Pie -- sorry I can't make the pi symbolwith the computer.
Pi =3.41592......
Radius is R and is squared (raised to the 2nd power)
Pi and radius squared are multipled
Area of a circle = Pi(Rsquared)

PIE multiplied by square root of R

A=π*r^2, where A=area and r^2 is r*r or r squared. You stated it correctly in English, and that is half the battle...all you need to do is write it down in the language of math and then you've got it!

The formula for finding the area of a circle would be πR² if you are given the radius.
It would be: πd²/4 if you are given the diameter.
It would be: C²/4π if you are given the circumference.

iTS REALLY SIMPLE THE EQUATIOUN IS pi r squared pi=3.14 and R= radius squared or twice and when you figure that out multiply it by the height.Your answer is pi r squared height{h}

it is pi and not pie. the result = pi *R^2

if you want to write it in EXCEL write this:
=PI(R^2)
where R = the cell number e.g. =PI(a3^2)
