Answer:
28.258mm
Step-by-step explanation:
A semi circle is half of a circle, so we will divide it by 2 after finding the area.
Formula for finding semi circle = pi x radius ÷ 2
Formula for radius = diameter ÷ 2
Radius = 36 ÷ 2 = 18mm
Semi circle = 3.14 or 22/7 x 18 = 56.57
56.57 ÷ 2 = 28.285
Note: I don't have a calculator with me right now, so you might want to consider typing out pi x 18 ÷ 2 on a calculator since my answer might be wrong because the answer has endless decimals.

Answer:
slope or m = -1
Step-by-step explanation:
The slope formula is:
y2-y1 -3 - 1 -4 -4
-------- = -------------- = --------- = ----- = -1
x2-x1 1 - (-3) 1+3 4
So, the slope is -1 XD YAY!!
