The circle shows the radius of 12mm what is the circumference
gulaghasi [49]

Answer:

24π or about 75.4 mm

Step-by-step explanation:

The circumference of a circle is denoted by C = 2πr, where r is the radius.

Here, we see that r = 12, so plugging this in:

C = 2πr

C = 2π * 12 = 24π ≈ 75.4 mm

The answer is thus 24π or about 75.4 mm.

Slope = \frac{8-4}{2-0}=2

y = 2x + b
