"Please Excuse My Dear Aunt Sally<span>". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".
</span><span> we follow PEDMAS simply because that's the accepted convention, but we have the convention because it fits common cases well and makes mathematical expressions easier to read.

I don't know exactly what answer you're looking for but that's what I got. This shouldn't have been hard to pick up on in class lol.
In terms of diameter (d), the area (A) of a circle is given by the formula
A = (π/4)d²
You have d=20 yd, so the area of the circle is
A = (π/4)×(20 yd)² . . . . substitute the given information into the formula
A = 100π yd² . . . . . . . . do the arithmetic
A ≈ 314.16 yd²
Answer:
4th option
Step-by-step explanation:
Each interval is 2 units. Because in between the two points there are 21 intervals, the range is 42 (21*2).
Answer: 16700
Step-by-step explanation:
First, we must factor 167^2-167*67
Factoring out 167 gives:
167(167-1*67)
Following Order of Operations, you get 167(167-67) which then gets 167(100)
Then, multiply and get 16700
