Answer: m = 0
Step-by-step explanation: To solve this problem, we don't even have to use our slope formula. It's important to understand that when we have the same <em>y</em> coordinate in our first ordered pair and our second ordered pair, this means that the line will be flat or horizontal.
When a line is horizontal, it means the line has a slope of zero.
We use the variable <em>m</em> to represent slope.
So here, we can say that <em>m = 0</em>.
Answer:
Area of the circular sidewalk = 405 m²
Step-by-step explanation:
Radius of the circular flower bed = 20 m
Area of the circular bed = πr²
Here r = radius of the circle
Area of the circular bed = π(20)²
= 400π square meter
Radius of the larger circle = Radius of the flower bed + width of the sidewalk
= 20 + 3
= 23 m
Area of the larger circle = π(23)²
= 529π m²
Area of the circular sidewalk = Area of the larger circle - Area of the flower bed
= 529π - 400π
= 129π
= 129(3.14)
= 405.06 square meters
≈ 405 square meters
