Question

Determine the area of the figure. (Hint: area of half circle plus area of

the triangle) The base of the triangle is 6cm and the radius of the circle
is 3cm. Round to the nearest tenth.
7
6 cm
3 cm

Answer 1

35.13

Rounded: 35.1

Explanation:

The figure will look like the attached image.

(My guess, based on hint)

We will first find the area of the circle.

Area of circle is radius squared times Pi

3x3x3.14=28.26

It is half circle so 28.26/2=14.13

The question didn't state the height, but the base is 6 and we'll assume it is 7 because the question has 7 in the third to last row. 7x6/2=21

14.13+21=35.13
