Answer:
h = 
Step-by-step explanation:
Area (A) of a triangle =
× base (b) × height (h)
i.e A =
bh
h = 
Answer:

Step-by-step explanation:
<u>1) Find the radius</u>
We can do this by using the distance equation with the centre (7,1) and the given point (-1,-5):
where the two points are
and 
Plug in the points (7,1) and (-1,-5)

Therefore, the radius of the circle is 10 units.
<u>2) Plug the data into the equation of a circle</u>
Equation of a circle (when not centred at the origin):
where the centre is
and r is the radius
Plug in the centre (7,1) as (h,k)

Plug in the radius 10

I hope this helps!
The total amount of lenght that the line will have depends on the amount of strips, and the result is equal to the multiplication of the amount of strips, x, and the length of the strips 3/8 inch
total_length = (3/8)x
where x is the amount of strips, and the total length is in inches
This is called diffusion.
