For the full circle, Area = pi(r)^2
pi x 1^2 = pi
Semi circle = pi/2 = 1.57 square feet
2.5 b = 27.5
b = 27.5 / 2.5
b = 11
Answer: Yes, it is correct
Step-by-step explanation: Because of that, When you multiply 4.2 x 3 x 4 = 50.4
Pick any value for x, like x = 0, plug it into the equation, and get the value for y. For x = 0,
2(0) + y = 5
y = 5
The ordered pair is (0,5). Find other ordered pairs using the same reasoning.
