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

40% of 196= 40% * 196= 0.4 * 196= 78.4
196
196 = 14² → √196 is rational.
196 feet of course. For a circle "perimeter" and "circumference" are just two words for the same thing.

Circumference of a circle: 2 x Pi x r (with r = the radius of the circle).Area of a circle: Pi x r x rThe circumference is 28, so:2 x Pi x r = 28r = 28 / (2 x Pi)Area = Pi x (28 / (2 x Pi)) x (28 / (2 x Pi)) = 62.4[rounded on one decimal] or more accurately (196 / Pi).

Circle area = Pi * r^2 r = d/2 Since d=28. r=14. 28^2 = 196 The area is 196 Pi or approximately 615.75 square feet.
The formula for area of a circle is pi r squared. so 14 squared is 196. Let's take pi to be 3.14, so 3.14 x 196 =615.44 metres squared.
If this circle is 28ft then: Area of a circle = pi time r2 A diameter of 28 feet means a radius of 14 feet Area = pi times 196 or 615.75 square feet
area of a circle = pi time r2 A diameter of 28 feet means a radius of 14 feet area = pi times 196 or 615.75 square feet
The area of a square cannot be 196 feet. If the area is 196 square feet (which is an entirely different thing) its sides are sqrt(196) = 14 feet.
Using 3.14 as Pi the area of circle is: 615.44
