In the diagram below, the circle has a radius of 25 inches. the area of the unshaded is 500pi in^2Determine and state the degree
Dmitriy789 [7]
72^{\circ}

1) In this question, we are going to make use of the formula for the area of that sector, to find the central angle.

2) So, let's write it out an expression involving the area of a circle, the unshaded area, and the shaded one and then plug into that the given data:

\begin{gathered} A=\frac{\alpha}{360^{\circ}}\times\pi r^2 \\ A_{Unshaded}+A_{shaded}=A_{Circle} \\ 500\pi+\frac{\alpha}{360}\times\pi r^2=\pi r^2 \\  \\ 500\pi+\frac{α}{360}\pi25^2=25^2\pi \\  \\ 500\pi+\frac{125\piα}{72}=625\pi \\  \\ 500\pi +\frac{125\pi α}{72}-500\pi =625\pi -500\pi  \\  \\ \frac{125\pi α}{72}=125\pi  \\  \\ \frac{72\times \:125\pi α}{72}=72\times \:125\pi  \\  \\ \frac{125\pi α}{125\pi }=\frac{9000\pi }{125\pi } \\  \\ α=72^{\circ} \\  \\  \end{gathered}

Thus, the centra angle of that shaded area is 72º

Komisyon (9-6) 12) Bir araba satıcısı, bir haftalık araba satışlarının% 2,5'ini ve saatine 30 dolar veriyor, haftalık satışları
Tresset [83]

Cevap:

3700 ABD doları

Adım adım açıklama:

Haftalık satış = 100.000 $

Haftalık satışlarda kazanılan yüzde =% 2,5 = (0,025 * 100.000 ABD Doları) = 2500 ABD Doları

Saatlik kazanç = 30 $

Çalışılan saat sayısı = 40 saat

Çalışılan saat için kazanç = 40 * 30 $ = 1200 $

Toplam kazanç:

Haftalık satış yüzdesi + çalışılan saat için kazanç

(1200 ABD doları + 2500 ABD doları) = 3700 ABD doları
