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
Where is the circumference of the circle
is a constant (Take
= 3.14)
and is the radius of the circle
From the question,
radius, = 3.88 in
Hence, the circumference, becomes
in
Hence, the circumference of the circle is 24.37 in
For the area of the circle,
Area of a circle is given by
Where is the area of the circle
Since, radius, = 3.88 in
The area of the circle then becomes
in²
Hence, the area of the circle is 47.27 in²
To solve for the inverse of the function given;
We begin by re-writing the function as follows;
To now find the inverse, we interchange y for x, and vice versa, as shown below;
We now find the value of y;
