What's the best Approximation? :3

musickatia [10]

Area of shaded region = Area of larger circle - Area of smaller circle.

We know, Area of a Circle = πr²
So, A = πr₁² - πr₂²
A = π (r₁² - r₂²)
A = π(10.2² - 5.4²)
A = 3.14 (104.04 - 29.16)
A = 3.14 (74.88)
A = 235.12

In short, Your Answer would be 235.12 cm²

Hope this helps!

Step-by-step explanation:

$\displaystyle 1\frac{119}{250} = \frac{1476}{1000}$

$\displaystyle 1\frac{1}{13} \times 7 = 7\frac{7}{13} ≈ 7,538461538 ≈ 7,5$

$\displaystyle \frac{41}{1\frac{1}{10}} = 37\frac{3}{11} ≈ 37,3$
