8/10 = 4/5 divide each by 2
Perimeter (P) = 2L + x
4900 = 2L + x ⇒ 4900 - x = 2L ⇒ = L
Area (A) = L · x
A = () (x)

Answer:
V ≈ 2011 cm³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = area of base × perpendicular height
V = πr²h ( r is the radius and h the height )
Here r = 8 and h = 10, thus
V = π × 8² × 10
= π × 64 × 10 = 640π ≈ 2011 cm³ ( to nearest whole number )
Slope of perpendicular is -1/3.
Then equation is
y-5=(-1/3)(x+9)
The distance between any two points is:
d^2=(x2-x1)^2+(y2-y1)^2
d^2=(6--2)^2+(4--4)^2
d^2=8^2+8^2
d^2=64+64
d^2=128
d=√128 units
