Answer:
For a circle of radius R, the perimeter is:
P = 2*pi*R
Where pi = 3.14
If we have a section of this circle, defined by an angle θ, the length of that arc is calculated as:
L = (θ/360°)*2*pi*R
In this case, we have a unit circle, so the radius is 1 unit, and we have a section defined by an angle of 57°.
Then the total distance traveled will be equal to the length of the arc, which is:
L = (57°/360°)*2*3.14*(1 unit) = 0.99 units
Then the correct option is a.
(as we want to find the total distance, the starting point does not matter, so the total distance traveled in a section of 57° would be the same in any point of the circle, this means that the fact that we should start at the point (1,0) has no effect in this question)
94 if your using the whole frame the math is 5×7=35 we have 2 sides do times 35 by 2 35×2=70 then we do 1×7=7 for the outside of the game then do 7 times 2 b/c you have 2 sides the do your final side by doing 5×1=5 then times that by 2 and you get 10 .70+14+10=94
If it's a "fill in the blank" kind of question, I think the answer is answer.

Answer:
131 in²
Step-by-step explanation:
Let x represent the length of the painting. Given that The width of a painting is 4 inches less than the length. Hence:
Width = x - 4
The area of painting = length * width = x(x - 4) = x² - 4x
The frame that surrounds the painting is 2 inches wide (at the top and bottom, left and right). Hence the total width of the frame = (x - 4) + 2 + 2 = x, the length of the frame = x + 2 + 2 = x + 4
The area of the frame = length * breath = x(x + 4) = x² + 4x
Given that the area of the frame = 240 in², hence:
x² + 4x = 240
x² + 4x - 240 = 0
x = -17.62 and x = 13.62
Since the length cannot be negative, hence length = x = 13.62 inches
Area of painting = x(x - 4) = 13.62(13.62 - 4) = 131 in²
