Answer:6.28 ft^2
Step-by-step explanation:
Diameter=4
Radius=diameter ➗ 2
Radius=4 ➗ 2
Radius=2
Area of semicircle=0.5xπx(radius)x(radius)
Area of semicircle=0.5x3.14x2x2
Area of semicircle=6.28 ft^2
(x - 1)(x - 4)(x + 7) = 0 ⇔ x - 1 = 0 or x - 4 = 0 or x + 7 = 0
x = 1 or x = 4 or x = -7
Answer: c. (1; 0); (4; 0); (-7; 0)
