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 answer depends on what the "36 inch" measures: inside circumference, radius, diameter?
Circumference = 2*pi*radius or diameter*pi
Circumference of a circle = 2*pi*radius or diameter*pi
The radius is 7 inches.
The radius of a circle with a 14.5 inch circumference is 2.15 inches
A circle with a 48-inch radius has a circumference of about 301.592 inches.
17.9936 inch
A circle with a radius of 3.4 inches has a circumference of 21.36 inches.
A circle with a radius of 3 inches has a circumference of 18.8 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 7-inch circle is: 21.99
The answer depends on what the "36 inch" measures: inside circumference, radius, diameter?
50.265"
If a circle has a circumference of 43.98 the radius is: 7 (6.999).
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
circumference = 2*pi*radius or pi*diameter
