Question

Find the Area of the figure below, composed of a rectangle and a semicircle.

Round to the nearest tenths place.

Answer 1

68.1 units²

Explanation:

Start by finding the area of the rectangle...

`Area=lw\\Area=6*9\\Area=54`

Then, find the area of the semicircle...

`Radius=(1)/(2)*Diameter=(1)/(2)*6=3`

`Area=(1)/(2)\pi r^2\\Area=(1)/(2)\pi 3^2\\Area=(1)/(2)\pi 9\\Area=(9)/(2)\ pi\\Area\approx14.1`

Now, add the two to get...

54+14.1=68.1
