A3 cm by 3 cm rectangle sits inside a circle with radius of 4 cm

41.24 cm²

Step-by-step explanation:

Here is the complete question:  A 3 cm by 3 cm rectangle sits inside a circle with radius of 4 cm. What is the area of the shaded region?

Given: measurement of rectangle is

          Radius of circle is 4 cm.

We can find the area of shaded region by subtracting area of rectangle from area of circle.

First, lets find the area of rectangle

Formula; Area of rectangle=

Area of rectangle=

∴ Area of rectangle= 9 cm²

Now, finding the area of circle.

Formula: Area of circle= (∵ r is radius)

Area of circle=

∴ Area of circle= 50.24 cm²

Next solving to find area of shaded region.

Area of shared region=

Area of shaded region=

∴ Area of shaded region= 41.24 cm²

just keep asking questions until you have a better understanding.
