Answer:
12.57 yards
Step-by-step explanation:
The circumference of a circle is denoted by:
, where d is the diameter.
Here, we are given the diameter, so d = 4.
Now, plug this into the equation:

≈ 12.57
The circumference is about 12.57 yards.
Hope this helps!
Answer:
21(11 +3x) or simplified more, would be: 231 + 63x
Step-by-step explanation:
P E M D A S
First, Do what is in the parethesis
7 x 3(5 x 2 + 3x + 1)
7 x 3(10 + 1 + 3x)
7 x 3(11 +3x)
Since there are no exponents move on to the next step.
Then multiply.
21(11 + 3x)
I didn't know whether if you were trying to put 5x(2) or not, so it got me confused! Sorry if this isn't right equation! But I hoped this helped!
If simplifies even more, it would be
231 + 63x
(If they wanted it to be in simpilest form)
Answer:
119.6 - 18.824x
Step-by-step explanation:
5.2 x 23 = 119.6
5.2 x 3.62x = 18,824x
= 119.6 - 18.824x
