find the circumference of a circle which diameter is 7.3
Answers
Answer:
Inputs:
Radius (r):
3.65
or
Diameter (d):
7.3
or
Area (A):
41.85
Unit of Lenght:
centimeter
Calculate Circumference
Result:
The circumference of a circle with diameter 7.3 is 22.93(*)
Formulas:
r = 3.65
d = 7.3
C = 22.9
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 = 2·3.14·3.65 = 22.93(*)
In terms of diameter:
Circumference = π·d = 3.14·7.3 = 22.92(*)
In terms of area:
Circumference C = √4·π·A = √4·π·41.85 = 22.93(*)
(*) 22.93 cm 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 22.93 centimeters is equal to:
0.0002293 kilometers (km)
0.2293 meters (m)
229.3 millimeters (mm)
0.00014248 miles (mi)
0.250766 yards (yd)
0.752297 feet (ft)
9.02756 inches (in)
Step-by-step explanation:
Answer:
Area of a circle in terms of radius:
Area = π·r2 = 3.14·3.652 = 41.85 square centimeters(*)
Area of a circle in terms of diameter:
Area = π·(d
