Answer:
Area = 3.5325 ft² ≈ 3.53 ft²
Perimeter = 7.71 ft
Step-by-step explanation:
This is a semi-circle so we just divide the circumference of the original circle by 2
C = 2πr
C = 2 * 3.14 * 1.5
C = 3.14 * 3
C = 9.42
9.42 / 2 = 4.5 + 0.21 = 4.71 ft
4.71 ft + 3 = 7.71 ft
Area:
A = πr²
A = 3.14 * 2.25
A = 7.065 ft²
7.065 ft² = 3.5 + 0.0325 = 3.5325 ft²

Answer:
x = 12
Step-by-step explanation:
5x - 30 = 2x + 6
3x = 36
x = 12
Answer:
y = -4x
Step-by-step explanation:
Find the slope (m) and the y-intercept (b) of the line. Thereafter, substitute the value of each into y = mx + b to get the equation of the line.
✔️Find the slope (m) using two points on the line, (-2, 8) and (0, 0):
Slope (m) = change in y/change in x
m = (0 - 8)/(0 - (-2))
m = -8/2
m = -4
✔️Find y-intercept (b):
Y-intercept = 0, this is where the line intercepts the y-axis.
b = 0
✔️Substitute m = -4 and b = 0 into y = mx + b:
y = -4x + 0
y = -4x
