Question

I need help with this problem ASAP!

Answer 1

4322.64 ft^2

Explanation:

Diameter:
`(radius)/(2)`

Area of circle:
`\pi r^2`- r = radius

Area of rectangle:
`l * w`- l = length, w = width

The area of the family's backyard is 110 × 50 = 5500 feet. Now, let's find the area of the circular swimming pool.

• Radius: 36/2 = 18
• 
  `3.14*18^2`
• 
  `3.14 * 324`
• 
  `1017.36`

Next, we find the area of the concrete walkway.

• 
  `40 * 4`
• 
  `160`

After that, we add the area of the circular pool and walkway.

• 
  `1017.36 + 160`
• 
  `1177.36`

Lastly, subtract 1177.36 from 5500.

• 
  `5500 - 1177.36`
• 
  `4322.64`

Therefore, the answer is 4322.64.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
