Sam forgot to multiply

If the diameter is 12 inches, the radius is 6 inches, because the radius is half the diameter.

Given the formula

$A=\pi r^2$

we have

$A=36\pi$

When you fold the circle in half, the resulting figure has half the area.

So, you start with a circle with area $36\pi$

You fold it once and you have a semicircle with area $18\pi$

You fold it twice and you have a quarter circle with area $9\pi$

Answer:

12.5cm

Step-by-step explanation:

This triangle is either isosceles or equilateral, we already know two sides.

the other side of the triangle is also 5 cm long because it is also the radius of the shape

the format for finding a right angle triangle like this one is base x height / 2

5 x 5 = 25

25/2 = 12.5

12.5 rounded is 13 because the decimal number is 5 and 5 or higher means we need to round up.

hopefully this helped
