FinnZ [79.3K]

Answer:

8 pi yd.

The circumference of a circle can be calculated as follows:

c = $2 \cdot \pi \cdot r$

Where r is the radius of the circumference.

So in our case:

Use foil which is a lazy way to remember theh distributive property
goes like this
multiply
First terms
Outer terms
Inner terms
Last terms
and add them all toegethe

so
(x+2)(x+2)
First: x times x or x²
Outer: x times 2 or 2x
Inner: 2 times x or 2x
Last: 2 times 2 or 4

add them toegether
x²+2x+2x+4=
x²+4x+4
