1. The perimeter of the square is 32 units, means each side is 32/4=8 units.

rotating the square about line k forms a cylinder with base radius equal to 8 units, and height equal to 8 units. (check the first picture)

the circumference of the base is C=2πR=16π units=16*3.14 units = 50.24 units.

Answer:  <span>a cylinder with a circumference of about 50 units

2. 
Rotating the equilateral triangle around line a, produces a cone with base radius equal to half of one side of the triangle, that is r=10mm.

(check picture 2)

The circumference is </span>C = 2πr=<span>C = 2*3.14*10=62.8 mm

Answer: </span><span>a cone with a base circumference of about 63 mm</span>

Find the inverse of the function f(x) = (x - 4) 2 - 5 if x ≥ 4.
Serggg [28]
Same here, we do a quick switcharoo on the variables first,

\bf \stackrel{f(x)}{y}=(x-4)^2-5\qquad inverse\implies \boxed{x}=\left( \boxed{y}-4 \right)^2-5&#10;\\\\\\&#10;x+5=(y-4)^2\implies \pm\sqrt{x+5}=y-4\implies \pm\sqrt{x+5}+4=y

A cylinder-shaped drainage pipe 66 in. long measures 25.12 in. around.
Darina [25.2K]
V=hpir^2

tricky, they didn't give us radius
they just gave circiufmerece

c=2pir
25.12=2pir
divide by 2 both sides
12.56=pir
divide by 3.14 both sides
4=r

subsitutet

v=hpir^2
v=66pi4^2
v=66pi16
v=1056pi
v=3315.84 cubic inches
