Question 3 of 14
kobusy [5.1K]

Answer:

\$84,000

Step-by-step explanation:

Remember that

6\%=6/100=0.06

we know that

The amount the salesman would earn in a year must be equal to the base salary multiplied by 12 (number of months in a year) plus 6% of the amount sold in merchandise in a year

so                                                

4,000(12)+0.06(600,000)=\$84,000

radius of the circle=12 cm / 2=6 cm

Area of the square=side²=(12 cm)²=144 cm²

Area of the four  sides between the square and the circle=

=Area of the square - area of the circle=144 cm²-113.112 cm²=30.888 cm²
