Answer:
The circumference of the circle is 24.37 in
The area of the circle is 47.27 in²
Step-by-step explanation:
The circumference of a circle is given by the formula
[tex]C = 2\pi r\\[/tex]
Where [tex]C[/tex] is the circumference of the circle
[tex]\pi[/tex] is a constant (Take [tex]\pi[/tex] = 3.14)
and [tex]r[/tex] is the radius of the circle
From the question,
radius, [tex]r[/tex] = 3.88 in
Hence, the circumference, [tex]C[/tex] becomes
[tex]C = 2\pi r\\[/tex]
[tex]C = 2(3.14)(3.88)\\[/tex]
[tex]C = 24.37[/tex] in
Hence, the circumference of the circle is 24.37 in
For the area of the circle,
Area of a circle is given by
[tex]A = \pi r^{2}[/tex]
Where [tex]A[/tex] is the area of the circle
Since, radius, [tex]r[/tex] = 3.88 in
The area of the circle then becomes
[tex]A = \pi r^{2}[/tex]
[tex]A = (3.14) (3.88)^{2}[/tex]
[tex]A = 47. 27[/tex] in²
Hence, the area of the circle is 47.27 in²
