Note: Consider we need to find the circumference and area of the given circle.
Given:
A circle with radius 7.1 m.
To find:
The circumference and area of the given circle.
Solution:
Circumference of a circle is:
[tex]C=2\pi r[/tex]
Putting [tex]r=7.1,\pi=3.14[/tex], we get
[tex]C=2(3.14)(7.1)[/tex]
[tex]C=44.588[/tex]
[tex]C\approx 44.6[/tex]
Therefore, the circumference of the circle is 44.6 m.
The area of the circle is:
[tex]A=\pi r^2[/tex]
Putting [tex]r=7.1,\pi=3.14[/tex], we get
[tex]A=3.14(7.1)^2[/tex]
[tex]A=158.2874[/tex]
[tex]A\approx 158.3[/tex]
Therefore, the area of the circle is 158.3 sq. m.
