Find the area of a circle with a diameter of 6. Either enter an exact answer in terms of pi or use 3.14 for pi
ankoles [38]
So it gives you the diameter but you need the radius of the circle to find the area so to find the radius you just divide the diameter by two. the formula for the area of a circle is A=pi*r^2 so you just multiply 3.14 by 3 squared so you just put it in the calculator as A=3.14*3^2 and you get 28.26 hope this helped
