1 answer:
Answer:
2644.415 feet spuared
Step-by-step explanation:
I think the attached photo is your full question, and my answer:
We need to find:
- the area of the pool = π = 3.14* = 1319.585 feet spuared.
- The area of the triangular fence = 1/2* 84*92 = 3964 feet spuared
So, the area of the backyard which is not covered by the pool is:
The area of the triangular fence - the area of the pool
= 3964 - 1319.585
= 2644.415
Hope it will find you well.

The population of Ohio will be 10 million in the year 1970
The population growth of Ohio is represented by the function:
P is the population in millions
t is the number of years since 1900
To find the year that the population of Ohio will be 10 million, substitute P = 10 into the function P(t) and solve for t
t = 70 years (to the nearest whole number)
70 years after 1900 will be 1970
Therefore, the population of Ohio will be 10 million in the year 1970
