A circle with a diameter of 14 feet

what is the area ?

May 1st, 2015

Area of a circle = pi *r^2 = 3.14 * 7^2 = 153.86  if you take pi = 3.14

May 1st, 2015

How many decimal points do you need it to round to?

May 1st, 2015

here is also a nice calculator on google, but it takes pi equal far more then 3.14, so it has more precise result, but it also depends on what you should have pi equal to in your assignment

you just type in radius ,


radius  = diameter/2
