The formula for the circumference of a circle is C = pi r2 where r is the radius. Substituting 56 inches for the radius gives: C = pi(56)2 = (3136)pi inches.
The circumference of a circle is its diameter times pi, which is the same as twice the radius times pi.A = 2r (pi)In this instance, the circumference is 32(pi) inches(about 100.53 inches)
the radius is 10.5 inches. * * * * * Wrong! Circumference = 2*pi*Radius Or, Radius = Circumference/(2*pi) So circumference = 21 inches implies radius = 3.34 inches (to 3 sf)
The circumference of a circle is 2*pi*r. With r = 3, the circumference is 6 pi.
The circumference of a circle that has a radius of 5 inches is 10 X pi or approximatly 31.415926535897932384626433832795. If you know the radius you can find the circumference by multiplying it by 2(pi)
Circumference = 2*pi*radius = 26*pi inches
Circumference = 2*pi*radius or circumference/2*pi = radius 90 inches/2*pi = 14 inches in radius =======================
Circumference of the circle if the radius is 12 inches is 2*pi*r = 24*pi = 75.398
Circumference of the circle: 2*23*pi = 46*pi inches
Circumference of a circle = 2*pi*radius or diameter*pi
Circumference of a circle = 2*pi*radius or diameter*pi
Circumference of a circle in inches = 2*radius*pi or diameter*pi Both radius and diameter must be in inches
The circumference of a circle when the radius is 3 inches is: 18.8 inches (r x 2 x Pi = circumference)
Circumference of a circle: 2*pi*radius or pi*diameter
The formula for the circumference of a circle is C = pi r2 where r is the radius. Substituting 56 inches for the radius gives: C = pi(56)2 = (3136)pi inches.
The circumference is about 43.98 inches. The circumference of a circle is diameter (radius x2) x pi (3.14).
Circumference = 2*pi*r = 34*pi inches.
