3cm/4ft=18cm/x

3x=4(18)

3x=72

x=24ft
the diameter of the circle is 24ft so the radius is 12ft
find the area of the circle with the radius
A=452.4ft squared

The actual area is 454.1 ft.

You can use a ratio to find the actual diameter:
18cm/3cm = x/4ft.
x = 24 ft.

Then find the area using A=pi*r^2
A=pi*144
A=452.4 ft.

What is an equation of the line that passes through the point (-5 7) and is parallel to the line x-5y=15
mafiozo [28]

Answer:

Step-by-step explanation:

Parallel lines have same slope.

y = mx + b

Slope = m  & y-intercept = b

x - 5y = 15

   -5y = -x + 15

      y = \frac{-1}{-5}x + \frac{15}{-5}\\\\

y = \frac{1}{5}x - 3

so, slope = 1/5   ; (-5 , 7)

y -y1 = m(x -x1)

y - 7 = \frac{1}{5}(x- [-5])\\\\y - 7 =\frac{1}{5}(x + 5)\\\\y - 7 = \frac{1}{5}x+5*\frac{1}{5}\\\\y - 7 =\frac{1}{5}x+1\\\\y =\frac{1}{5}x+1+7\\\\y=\frac{1}{5}x + 8
