Answer:
Area of square with a side of 2r = 2(1) = 2 = 2^2 = 4
Area of circle = pi ( 1)^2 = pi
x = pi / 4 ≈ .79 = 79%
Answer:
b
Step-by-step explanation:
Because of rules of geometry we know that a+b=180 degrees so we can add the equations together and set that equal to 180 and solve
6x-48+4x+38=180
subtract 38 from both sides and add 48 to both sides
then add like terms
10x=170
and divide by 10 to get
x=17
645/560=1.151785714
Ther perccent error in her estimate is 15%
Answer:
1/9th.
Step-by-step explanation:
Because the area is measured in units squared, then you have to square 1/3 which is 19th.
