We Know,
[tex]\:\mathsf{Perimeter\: of\: circle\: = 2πr}[/tex]
We are given with radius of the circle i.e. 90 m
Now,
Perimeter of circle = 2πr
= 2(3.14)(90)
= 565.2 m²
Hope this helps you!
The circumference of a circle with radius 90 is 565.56
Formulas:
[tex]C=2*\pi *r[/tex].
[tex]C=\pi *d[/tex]
[tex]C=\sqrt{4*\pi *A}[/tex]
[tex]\pi =3.1415[/tex]
[tex]A=[/tex] [tex]area[/tex] [tex]of[/tex] [tex]a[/tex] [tex]circle[/tex]
[tex]C=circumference[/tex] or [tex]perimeter[/tex]
[tex]r=radius,d=diameter[/tex]
Step-by-step Solution:
Circumference of a cicle in terms of radius:
Circumference [tex]=2*\pi*r=2*3.[/tex] [tex]14*90=565.56[/tex]
In terms of diameter:
Circumference [tex]=\pi*d=3.14*180=565.2[/tex]
In terms of area:
Circumference [tex]C=\sqrt{4*\pi*A}=\sqrt{4*\pi*25450} =565.56[/tex]
Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.
A circumference of 565.5 meters is equal to:
- 0.5655 kilometers (km)
- 56550 centimeters (cm)
- 565500 millimeters (mm)
- 0.351385 miles (mi)
- 618.438 yards (yd)
- 1855.31 feet (ft)
- 22263.8 inches (in)
