This figure is made up of a triangle and a semicircle.
What is the area of this figure?
Use 3.14 for pi. Round only your final answer to the nearest tenth.
Enter your answer as a decimal
_units2

Step-by-step explanation:

The formula for determining the area of a triangle is expressed as

Area = 1/2 × base × height

Base = 3 units

Height = 6 units

Area = 1/2 × 3 × 6 = 9 units²

The formula for determining the area of a semicircle is expressed as

Area = 1/2 × π × r²

Where

π is a constant whose value is 3.14

r represents the radius of the semicircle.

Diameter = 3 units

Radius = diameter/2 = 3/2

r = 1.5 units

Area = 1/2 × 3.14 × 1.5² = 3.5units²

Area of the figure is

9 + 3.5 = 12.5 units²

not sure but it may be b, as i said i'm not sure.

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
