The circumference of a
circle is 28.26cm. Find the
diameter and radius of the
circle.

The answers are:

Radius: 4.49771869

Diameter: 8.99543738

Step-by-step explanation:

Circumference Formula

C=2πr

28.26=2·π·r

28.26=(6.28318531)·r

28.26/28.26=6.28318531/6.28318531·r

r=4.49771869

d=4.49771869·2

d=8.99543738

Check

C=2πr

28.26=2π(4.49771869)

28.26=(6.28318531)·(4.49771869)

28.26=28.26 ✔

Hope this helps, and I'm sorry if I'm wrong. ;D

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
