A semicircle's perimeter is half the perimeter of the complete circle.

The perimeter of the complete circle is its circumference which is found by the equation: πD.

Then the equation of the perimeter of the semicircle is πD/2

In this case D = 24 in, then the perimeteir is π (24in/2) = 12π in ≈ 37.7 in

Answer: The exact length is 12π inches and the approximate length is 37.7 inches

Well on this problem recall area of a rectangle is defined by:

A = lw our w = 1/6 and our l = (x + $\frac{2}{3}$ ) we have let 'x' represent our original length.
$(x + \frac{2}{3} )( \frac{1}{6} )= \frac{11}{72}$
$\frac{1}{6} x+ \frac{2}{18} = \frac{11}{72}$
12x + 8 = 11
12x = 11 - 8
12x = 3
x = $\frac{3}{12} = \frac{1}{4}$ So our original length is $\frac{1}{4}$

Monica graphed the line y=3×+2.Janice graphs the second line that is parallel to monica's and passes through (-2,0). What is the

The equation of a line that passes throug the point (x1,y1) and has a sloppe of m is
y-y1=m(x-x1)

the slope of paralell lines ar the same

y=3x+2
y=mx+b
m=slope
m=3

a point is (-2,0)
slope is 3

y-0=3(x-(-2))
y=3(x+2)
y=3x+6
the equation is y=3x+6
