-2p-4=2, add 4 on both sides -2p=6, divide by -2 on both sides to get p=-3
Hope this helps!!

The equation of the segments perpendicular bisector is; y = -¹/₂x + 2
<h3>How to find the equation of the perpendicular bisector?</h3>
i) Since it is a perpendicular bisector, hence point M is the midpoint. Thus;
Midpoint (AB) = [(x₁ + x₂)/2], [(y₁ + y₂)/2] = (x_m, y_m)
Slope AB will be;
m₁ = ((x₁ - x₂)/(y₁ - y₂))
Slope of perpendicular bisector is;
m₂ = -1/m₁
Equation of perpendicular bisector is;
(y - y_m) = m₂(x - x_m)
ii) Midpoint (AB) = [(-2 + 6)/2], [(3 - 1)/2] = (2, 1)
Slope AB will be;
m₁ = ((6 + 2)/(-1 - 3)) = -2
m₂ = -1/-2 = 1/2
Equation of perpendicular bisector is;
(y - 1) = -¹/₂(x - 2)
y - 1 = -¹/₂x + 1
y = -¹/₂x + 2

Answer:
28.26 cm^2
Step-by-step explanation:
A = (pi)r^2
A = 3.14 * (3 cm)^2
A = 3.14 * 9 cm^2
A = 28.26 cm^2
