Basically
Circumference = 2 * pie * radius
To get the radius u need to measure the circles distance. For example I measured a circular mirror and the distance was 10cm. This is the diameter. To get the radius I’ll divide by 2 because the radius is from the centre of the circle to the edge. So, 10 divided by 2 = 5cm. The radius is 5cm. Now,
Circumference = 2 * pie * r
r = 5. Pie = 3.14
Circumference = 2 * 3.14 * 5
= The answer
****pie is always 3.14
I hope you understood
Answer:
C
Step-by-step explanation:
Given
3
= 24 ( divide both sides by 3 )
= 8
Raise both sides to the power of 
x + 9 = 
= ![(\sqrt[3]{8}) ^{4}](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7B8%7D%29%20%5E%7B4%7D)
= 
= 16 ( subtract 9 from both sides )
x = 7 → C
Angle 1 and angle 2 are a linear pair, which make a sum of 180
angle 2=180-angle 1=180-70=110
All real numbers is the correct answer.
