A= pi(r)^2C=pi*dr= 1/2(d)Area=196piSince you know that 196 has to be squared because of the Area formula, to find the radius, you take the square root of the number, this number is the radius of the circle. You also know that the circumference is pi times the diameter and you know the radius is half the diameter, or the diameter is twice the radius.sqrt(196)=1414=rd=28Circumference= 28pi
