I think the answer would be 31°
Answer:
D. (6,6)
Step-by-step explanation:
Given the system of two equations

1. Add these two equations:

2. Subtract these two equations:

Hence, the solution to the system is (6,6)
45 feet. 4 x 10 =40 then add the other half an inch to get the total of 45 feet or you could say 9 x 5= 45
Answer:
3π sq.feet
Step-by-step explanation:
Area of the square = L²
L is the length of the square
Given
Area of the square = 12 ft square
12 = L²
L = √12
L = 2√3 feet
Since the circle is inscribed in the square, the length of the square will be the diameter of the circle;
Area of the circle = πd²/4
Area of the circle = π(2√3)²/4
Area of the circle = 12π/4
Area of the circle = 3π sq.feet
19 times 3 equals = 57ft squared. Area = 57ft squared
