Radius = Circumference/(2*pi)
and then
Area = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)
Radius = Circumference/(2*pi)
and then
Area = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)
Radius = Circumference/(2*pi)
and then
Area = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)
Radius = Circumference/(2*pi)
and then
Area = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
Radius = square root of (area/pi) Circumference = 2*pi*radius
S = C2/pi where S is the surface area, C is the circumference.
Circumference = pi*d Area = pi*d2/4 So 4*area = pi*d2 4*area/Circumference = pi*d2/(pi*d) = d
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
The circumference is 4pi
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
Radius = square root of (area/pi) Circumference = 2*pi*radius
If circumference(C) is given, then r = C/2(pi) If area(A) is given, then r = (A/pi)1/2
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
S = C2/pi where S is the surface area, C is the circumference.
Circumference = pi*d Area = pi*d2/4 So 4*area = pi*d2 4*area/Circumference = pi*d2/(pi*d) = d
Given diameter = d: circumference = pi*d Given area = a: circumference = 2*sqrt(pi*a) Given an arc of length L subtends an angle x degrees at the centre: circumference = 360*L/x
Divide the cirumference by 3.14
3.14 to the 2 power
