$\bf \huge \: given$

• a 12cm by 2cm rectangular sits inside a circle with radius of 8cm

Is the shaded area what is left outside the rectangle and bounded by the circle?

If so,

$\bf \huge \: find \: it$

find the area of the rectangle $\bf \:= 12×12 = 144 unit^2$

the area of the circle =

$\bf \:π×r^2 = 3.14×8^2 = 201.06 unit^2$

(rounded to the nearest hundredthwhat is the area of the shaded region)

then the "shaded area" is the difference

$\bf \:201.06 - 144 = 57.06 unit^2$

Answer 2

Given:- A 12cm by 2cm rectangular sits inside a circle with radius of 8cm.

To find:-Area of shaded region =?

_________________

Area of the rectangle

12×12=144sq.unit

⚫️Area of the circle

[tex] πr^{2} \\ 22/2×8^{2}\\ = 201.06 unit^{2} [/tex]

------------------------------------

shaded area ◻️

= 201.6+144

=57.06 sq unit.
