Area of a circle : π * r²
4+1 = 5
π * 5² = 78.53
π * 4² = 50.27
78.53 - 50.27 = 28.26
The area of the border is 28.26 ft²
The maximum number of shrubs (x) = a(area) divided by 15.9
a(area)=37.1*15
37.1*15= 556.5
556.5/15.9=x
556.5/15.9=35
35=x
Answer:
x = 47.4
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj / hyp
cos x = 8.8 / 13
Take the inverse cos of each side
cos ^-1 ( cos x) = cos ^-1( 8.8 /13)
x = cos ^-1( 8.8 /13)
x =47.39633319
Rounding to the nearest tenth
x =47.4
