A circle is 360 degrees.
Answer:
y=-2x-12
Step-by-step explanation:
y-y1=m(x-x1)
y-(-2)=-2(x-(-5))
y+2=-2(x+5)
y=-2x-10-2
y=-2x-12
The lateral surface area consists of 2 sides with 11 unit long and 4 unit high, and 2 sides with 8 unit long and 4 unit high. Each side is a rectangle. So basically you use area of rectangle to determine the lateral surface area
lat sa = 2 × area of rectangle + 2 × area of rectangle
In this case, it will be
lat sa = (2 × l × h) + (2 × w × h)
lat sa = (2 × 11 × 4) + (2 × 8 × 4)
lat sa = 88 + 64
lat sa = 152
The lateral surface area is 152 squares unit
