Answer:
![178.98\ \text{m}^2](https://tex.z-dn.net/?f=178.98%5C%20%5Ctext%7Bm%7D%5E2)
Step-by-step explanation:
d = Diameter of flower bed = 16 m
Thickness of sidewalk = 3 m
r = Radius of flower bed = ![\dfrac{d}{2}=\dfrac{16}{2}=8\ \text{m}](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7B2%7D%3D%5Cdfrac%7B16%7D%7B2%7D%3D8%5C%20%5Ctext%7Bm%7D)
R = Radius of flower bed with sidewalk = ![8+3=11\ \text{m}](https://tex.z-dn.net/?f=8%2B3%3D11%5C%20%5Ctext%7Bm%7D)
The required area is given by
![A=\pi(R^2-r^2)\\\Rightarrow A=3.14\times (11^2-8^2)\\\Rightarrow A=178.98\ \text{m}^2](https://tex.z-dn.net/?f=A%3D%5Cpi%28R%5E2-r%5E2%29%5C%5C%5CRightarrow%20A%3D3.14%5Ctimes%20%2811%5E2-8%5E2%29%5C%5C%5CRightarrow%20A%3D178.98%5C%20%5Ctext%7Bm%7D%5E2)
The radius of the sidewalk is

1 Kilogram = 2.2 Pounds
200 kg * 2.2 = 440 pounds
440 pounds < 500 pounds
500 pounds weighs more
Answer: $23,600. ; $318,600
Step-by-step explanation:
From the question, we are informed that a house on the market was valued at $295,000 and after several years, the value increased by 8%.
The value of the increase will be 8% of $295,000. This can be mathematically written as:
= 8% of $295,000
= 8/100 × $295,000
= 0.08 × $295,000
= $23,600
The current value of the house will be:
= $295,000 + $23,600
= $318,600
I believe the ultimate fenced in area with minimal perimeter is a square.
For any geometric shape a circle has the greatest maximum area minimum perimeter ratio.
So for 420 meters, a square with sides of 105 meters will enclose maximum area if you must fence in a rectangular shape.
