Circumference = pi*d Area = pi*d2/4 So 4*area = pi*d2 4*area/Circumference = pi*d2/(pi*d) = d

area from circumference area = ( circumference2 / (4 * pi) ) area = 2.865 square feet (approx)

If the area is a circle, the circumference is 0.28 miles.

A = C^2/(4 pi) The area of the circle is... The circumference squared... divided by 4... divided by pi If you already know the area, then you can multiply it by 4*pi, and then the square root of the product is equal to the circumference! C = (A*(4 pi))^(1/2)

If its diameter is 4 units in length then:- Area of circle: pi*2^2 = 4*pi square units Circumference of circle: 4*pi units

Area = (Circumference)2/(4*pi)

Area = circumference squared... You do circumference divided by 4,... and then divide that by Pi.

Circumference = pi*d Area = pi*d2/4 So 4*area = pi*d2 4*area/Circumference = pi*d2/(pi*d) = d

Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)

area from circumference area = ( circumference2 / (4 * pi) ) area = 2.865 square feet (approx)

The circumference is 4pi

If the area is a circle, the circumference is 0.28 miles.

If the area is a circle with a four-mile circumference, the area in acres is: 814.72 acres.

radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi

A = C^2/(4 pi) The area of the circle is... The circumference squared... divided by 4... divided by pi If you already know the area, then you can multiply it by 4*pi, and then the square root of the product is equal to the circumference! C = (A*(4 pi))^(1/2)

area = π x radius2 ⇒ radius = √(area ÷ π) circumference = 2π x radius ⇒ circumference = 2π x √(area ÷ π) ⇒ circumference = √(4π2 x area ÷ π) ⇒ circumference = √(4π x area) So knowing the area, the circumference can be calculated by taking the square root of the area multiplied by 4 times π Example: What is the circumference of a circle with area 78.54cm2 Circumference = √(4π x area) = √(4π x 78.54cm2) ~= 31.42cm

Area of the circle = (circumference)2 / (4 pi)Area = 0.0796 circumference2(rounded)
