What is the circumference of a circle with diameter 7 inches?
Here is the answer to questions like: how to find the perimeter of a circle with diameter 7 inches?
Circle Calculator
Circumference Area
Inputs:
Radius (r):
3.5
or
Diameter (d):
7
or
Area (A):
38.48
Unit of Lenght:
Calculate Circumference
Result:
The circumference of a circle with diameter 7 is 21.99(*)
Formulas:
r = 3.5
d = 7
C = 22
C = 2·π·r C = π·d C = √4·π·A π = 3.1415
A = area of the circle
C = circumference or perimeter
r = radius, d = diameter
Step-by-step Solution:
Circumference of a cicle in terms of radius:
Circumference = 2·π·r = 2·3.14·3.5 = 21.99(*)
In terms of diameter:
Circumference = π·d = 3.14·7 = 21.98(*)
In terms of area:
Circumference C = √4·π·A = √4·π·38.48 = 21.99(*)
(*) 21.99 inches exactly or limited to de precision of this calculator (13 decimal places).
Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.
A circumference of 21.99 inches is equal to:
0.000558546 kilometers (km)
0.558546 meters (m)
55.8546 centimeters (cm)
558.546 millimeters (mm)
0.000347064 miles (mi)
0.610833 yards (yd)
1.8325 feet (ft)
