Answer:
x=-9/a and a=-9/x
Step-by-step explanation:
Formula to find the area of the sector is:
Where r= radius and \theta= central angle.
Given, radius is 4 centimeters has a central angle of 30'.
So, we can plug in r=4 and \theta=30° in the above formula to get the area of circle. So,
A= 16*15
A= 240
So, the area of sector is 240 square centimeters.
Based on the information given you would need to multiply 24 by 3 to get 72 cups. you would also need to multiply 18 by 4 to get 72 napkins. so you would need 4 napkin packages and 3 cup packages.
