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
Answer:
The correct answer is Option D. 20
Step-by-step explanation:
From the figure we get,
<RUS = 90° because RU ⊥ TS
<u>To find the value of x</u>
It is given that <RUS = 4x + 54
Therefore we can write,
4x + 54 = 90
4x = 90 - 54 = 36
x = 36/4 = 9
<u>To find RS</u>
It is given that,
RS = 3x - 7 = 3*9 -7 = 20
Therefore the correct option is Option D . 20
