To find area of full circle
A= pi*r^2
A=pi*20^2
A=1256 ft^2
Now figure only for the 3/4 of circle the building don’t cover
A=1256*.75
A=942 ft^2
So the area it can detect is 942 ft^2
Answer:
38.13 m²
Step-by-step explanation:
area of triangle = 1/2 base × height
= 1/2 × 4 × 3
= 6 m²
Area of rectangle = length × width
= 6 × 3
= 18m²
Area of semi circle = 180/360 × π × radius²
= 180/360 × 3.14 × 3²
= 14.13 m²
Add all the areas together
6 + 18 + 14.13 = 38.13
“Average rate of change” is the fancy way to say “slope.”
Sketch a graph and put two points with the same y-value, say (2,5) and (7,5).
How much rise is there between those two points? Since they have the same y-value there is no rise at all. You have a horizontal line.
The slope of a horizontal line is 0.
3-4z=-5+8z
Add 5 to both sides
8-4z=8z
Add 4z to both sides
8=12z
Divide both sides by 12
z=12/8
Simplify
z=3/2
