Answer:
D
Step-by-step explanation:
<em>y</em><em>=</em><em>kx</em><em>+</em><em>m</em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>
In this case I think the slope would be k.
<em>k</em><em>=</em><em>y2</em><em>+</em><em>y1</em><em> </em><em>/</em><em> </em><em>x2</em><em>+</em>x1
(4,-1) and (-1,4)
k=(4-1)/(-1-4)= 3/-5= -0.6 which is about -1
The shaded portion area A corresponds to the area Ao of the outer circle minus the area Ai of the inner circle:
A = Ao - Ai
Also, the area of each circle of radius r is given by:
π r²
where the radius r is half the diameter d.
So, using r = d/2 in the above formula, we obtain:
π r² = π (d/2)² = (π/4) d²
Now, replacing each area with the corresponding diameter, we find:
A = Ao - Ai
= (π/4) 4² - (π/4) 1.5²
= (π/4) (4² - 1.5²)
= (π/4) (16 - 2.25)
= (π/4) (13.75)
≅ 10.799
Rounding the result to one decimal place, we find the answer:
10.8 m²
