Area of any circle = pi*radius squared
The equation for a circle is PiD. The diameter is double the radius, so it is 7 yards in this case. The circumference is 7*PI. Which is approximately 21.98.
The area is 154 cm2
The area of a circle is equal to pi*r2, where pi is the radius. In this case, the area is equal to pi*(7 feet)2, which is about 154 square feet.
A circle with a radius of 7 meters has an area of 153.94 square meters.
Area of any circle = pi*radius squared
Because it has a radius, I'm assuming the area is a circle. The formula of area for a circle is A = pi*r2, so in this case the area is about 154 square yards.
Oh, dude, okay, so the area of a circle is Οr^2, and the circumference is 2Οr. Since the diameter is 7 yards, the radius is half of that, which is 3.5 yards. So, the area would be approximately 38.48 square yards, and the circumference would be around 21.99 yards. But hey, who's counting, right?
Radius = 43.96/(2*pi) = 6.996451298 or about 7 yards

3850m is the area of the a circle whose radius of 7meaters
The radius are 7 centimeters and the area are 153.93804002589985 square centimeters.
Diameter = 2 x radius = 7 yardsCircumference = Diameter x pi = 7 pi = 21.99 yards (rounded)
Circumference is 2π times the radius. So, for 14π the radius is 7. Area is πr2, so the area of a circle with radius 7 is 72π, or 49π (153.93).
The relationship between the radius and area of a circle is as follows: Area of circle = 3.14 x Radius x Radius or 22/7 x Radius x Radius
Area of a circle = (pi) x (radius)2 (pi) = about 3.1416 or about 22/7 . (It can never be written down exactly.) (radius)2 = (radius) x (radius)
