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:
a = 19
Step-by-step explanation:
-2(a + 3) = -4a + 32
-2a - 6 = -4a +32
<u> +2a +2a </u>
-6 = -2a + 32
<u>-32 -32</u>
-38 = -2a
divide by -2
<u><em>a = 19</em></u>

Answer:
r = 4.908
Step-by-step explanation:
V = 885
height (given in the picture) = 11.7
V = 
h
V = (3.14)(
)(h)
885 = (3.14)()(11.7)
885/3.14/11.7 =
Take the square root and you get 4.908.
