1 length is 4.75 feet
42 lengths = x feet Cross multiply
1 * x = 42 * 4.75 Multiply on the right
x = 199.5
amount left = amount started with - amount amount used
Amount left = ???
Amount started with = 240 feet.
Amount used = 199.5 Substitute
Amount left = 240 - 199.5 Subtract
Amount left = 40.5 Answer

(14,2)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Area of circle = 56 cm²
πr² = 56
3.14r² = 56
r²=56/3.14
r²= 17.83
r = √17.83
r = 4.22 cm
The diameter of the circle = diagonal of the square
Diagonal of the square = 2 * 4.22 = 8.44 cm
x² + x² = 8.44²
2x² = 71.2336
x² = 71.2336/2
x² = 35.6168
x = 5.967 cm
