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
As Option is nearest to our answer,
that means it will be right.
So,
Answer will be (c) 70686 ft.²
Answer:
What?
Step-by-step explanation:
Answer:
A = 213.52
Step-by-step explanation:
A = 4 pi radius square
diameter = 34
radius is half of diameter
radius = 17
A = 4(pi or 3.14)(17)
A= 213. 628300444 with pi
A = 213.52 with 3.14
hopefully this helps you understand this concept
