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

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
