Answer:
0.2146
Step-by-step explanation:
From the picture:
The radius of the circle = r. This means that the area of the circle = πr²
Also For the square, the length of the square = 2r, Therefore the area of the square = Length × length = 2r × 2r = 4r²
The area inside the square but outside the circle = Area of square - Area of circle = 4r² - πr² = r²(4 - π) = 0.8584r²
The ratio of the area inside the square but outside the circle to the area of the square = r²(4 - π) / 4r² = (4 - π) / 4 = 1 - π/4 = 0.2146

Answer:
30%
Step-by-step explanation:
70% of 120 is 84. So take the remainder of 70 (30, as %'s go up to 100.) and that's the percent left. We can "fact check this" the other way around as well.
30% of 120 = 36.
84 + 36 = 120.
The price of the boots have changed/raised 30%.
