The radius of the small circles is x.
The radius of the large circle is 2x.
Area of large circle:
πr² = π(2x)² = π4x² = 4πx²
Area of 1 small circle:
πr² = πx²
Area of 2 small circles:
2πx²
shaded area = area of large circle - area of 2 small circles
shaded area = 4πx² - 2πx²
shaded area = 2πx²
57.
The radius if the circle is x√2.
The side of the square is 2x.
Area of circle:
πr² = π(x√2)² = 2πx²
Area of square:
s² = (2x)² = 4x²
shaded area = area of circle - area of square
shaded area = 2πx² - 4x² or (2π - 4)x²

Answer:
150 pounds
Step-by-step explanation:
1.20 euros = 1 pound
180 euros = x pounds
Set up the proportion
1.20 Euros/1 pound = 180 Euros / x pound Cross multiply
1.20*x = 1 * 180 Combine
1.20 x = 180 Divide by 1.2
x = 180 / 1.20
x = 150 pounds.
As a bonus, you might want to try and guess which is the stronger currency.
