Question

Write an expression in terms of Pi that represents the area of the shaded part of N.

Answer 1

Answer:

The area of the shaded part is:

`=(PN)^2\lbrack\pi-(1)/(2)(75-\sin 75)\rbrack`

Step-by-step explanation:

The area of the shaded part is the subtraction of the area of the unshaded part from the area of the whole circle.

Area of the ushaded part is:

`(1)/(2)*(PN)^2*(75-\sin 75)`

Area of the circle is:

`(PN)^2\pi`

Area of the shaded part is:

`\begin{gathered} (PN)^2\pi-(1)/(2)(PN)^2(75-\sin 75) \\ \\ =(PN)^2\lbrack\pi-(1)/(2)(75-\sin 75)\rbrack \end{gathered}`
