Question

I need help with this problem ASAP!

Answer 1

Answer:

4322.64 ft^2

Step-by-step explanation:

Diameter: $\frac{radius}{2}$

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! ♡
