The circumference of a circle is nothing but the perimeter of a circle.
Circumference = 2pi(r)
where r = radius

**Circumference** = **2pi(r)**
However, this formula is only for full circles.
If we want to find the circumference of a semicircle, then we'd do: (pi(r)^2)/2
because a semicircle is half of a full circle

If we want to find the **circumference** of a **semicircle**, then we'd do: **(p...
So substitute the radius into this formula and solve
Ping me when you get the answer! I'll check if it's correct or not.

u got it..?

**Circumference** = **2pi(r)**
that's the area
Circumference = 2pi(r)
