Step-by-step explanation:
<em>I think you have forgotten to attach the question. </em>
<em>Anyways....</em>
In order to find the area of a circle use the formula:
π
Where r is the radius
For example the radius is 3cm. The area of the circle will be:
π × 
Since you have taken pi as 3.142...
3.142 ×
3.142 × 9
= 28.278
In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.
= 28.3 
The number of seats sold cannot be negative, so you have
... x ≥ 0, y ≥ 0
The limits on numbers of seats must be observed, so you have
... y ≤ 2000
... x + y ≤ 3000
And the revenue constraint must be met:
... 35x + 50y ≥ 90,000
Together, these inequalties are ...
{x ≥ 0, y ≥ 0, y ≤ 2000, x + y ≤ 3000, 35x + 50y ≥ 90,000}
Answer:
200 tiles
Step-by-step explanation:
area of the floor = 2m×4m
the tile=20cm×20cm
the tiles needed to complete the job will be
2m×4m
——–—–
20cm×20cm
change the meters to centimeters
200cm×400cm
————————
20cm×20cm
therefore the answer is 200tiles.
Step-by-step explanation:
you start with 90 then 180 then270 then 360
73+42 is correct because it’s addition
