Answer:
C = 6.28
A = 3.14
Step-by-step explanation:
use the equations for area and circumference to solve
C = pi d
A = pi r^2
I like to remember these using the saying Cherry pie's delicious, Apple pie's are too so Cherry = pi's delicious, Apple = pi's r 2
so with the diameter of 2 plug in to get circumference
C = 3.14 (2)
C = 6.28
and the equation for area uses radius not diameter but we know that d/2=r so radius is 1, plug in to solve
A = 3.14 (1)^2
A = 3.14 (1)
A = 3.14
Hope this helps! :)
Answer:
fourth option
Step-by-step explanation:
note that (
)(x)x) =

where x ≠ 0, - 
Answer:
x=52
Step-by-step explanation:
One of the properties of parallelograms is that angle A = Angle C
5y-54 = 3x eq1
Another property of parallelograms is that angle A + angle B = 180 degrees
5y-54+2y-60 = 180
7y = 180+114 = 294
y = 42
Putting this value in eq1
3x = 5*42-54 = 210-54 = 156
x = 52
Because is division is before multiplication you have to do division even though the m is before d.
