The area of a circle is 113.10 what is the radius

See attachment for C and E

Step-by-step explanation:

Given

--- Origin

--- distance of C to O

Solving (a): Plot point C

Calculate the coordinates of C using distance formula:

Where:

---

--

So, we have:

Square both sides

For this solution, we assume y = 0

Solve for x

So, the coordinates of C is: (1,0)

Solving (b): Plot point E

We have that E is 4/5 closer to the origin.

This implies that, the ratio is:

Multiply by 5

So, E is at 4:1 between O and C

Calculate the coordinates of E using:

Where
