Answer:

B. 24 inches by 30 inches

Step-by-step explanation:

Since the poser is similar to a rectangle measuring 8 in. by 10 in., we have to find which solution has the same proportions.

When simplified, 8/10 = 4/5. That is our proportion.

A) 2/2 does not equal 4/5

B) 24/30 (when simplified) = 4/5

B is our right answer because when 8 is multiplied by 3, you get 24 and when 10 is multiplied by 3 as well (both multiplied by the same number to keep the proportions the same) you will get 30.

Reference attached image for the problem.Please show your work for finding the partial area.

-Dominant- [34]

To find the area of a sector of a circle use the next formula:

$A=\frac{\theta}{360º}*\pi *r^2$

As the given circle has a outside angle 90º (it is not part of the sector of the circle) subtract the 90º from 360º (total angle of a circle) to find the angle of the sector:

$\theta=360º-90º=270º$

Find the area of the sector with angle 270º:

$\begin{gathered} A=\frac{270º}{360º}*3.14*(11in)\placeholder{⬚}^2 \\ \\ A=0.75*3.14*121in^2 \\ \\ A=284.955in^2 \end{gathered}$ Then, the approximate area of the given sector of a circle is 284.955 square inches
