Answer:
4
Step-by-step explanation:
1/3 of 30 is 10 and 2/5 of 10 is 4. Thats Your Answer.
Let R = 250 ft. & r = 200 ft.
Now, Area of Gravel Path =
= πR² - πr²
= π(R²-r²)
Area of Gravel Path =
π ( 250² - 200² )
π ( 62500 - 40000 )
π ( 22500 )
Taking π as 3.14
![π \times 22500 \\ 3.14 \times 22500 \\ \frac{314}{100} \times 22500 \\ 314 \times 225 = 70650 \: f {t.}^{2}](https://tex.z-dn.net/?f=%CF%80%20%5Ctimes%2022500%20%5C%5C%203.14%20%5Ctimes%2022500%20%5C%5C%20%5Cfrac%7B314%7D%7B100%7D%20%5Ctimes%2022500%20%5C%5C%20314%20%5Ctimes%20225%20%3D%2070650%20%5C%3A%20f%20%7Bt.%7D%5E%7B2%7D%20)
As Option is nearest to our answer,
that means it will be right.
So,
Answer will be (c) 70686 ft.²
