3/5=24/x. cross multiply, you get 120=3x. divide by 3, x = **40**
The area of circle is 379.94 cm².
Step-by-step explanation:
Given,
Radius of circle = 11 centimeters
We have to calculate the area of circle.
We know that;
Area of circle = 
Here;
π = 3.14 , r = 11
Area of circle = 
Area of circle = 3.14*121
Area of circle = 379.94 squared centimeters
The area of circle is 379.94 squared centimeters.

I agree with the author. By using the metric system we know the exact amount of a medicine we took, whether it's in mg or mL. This way every doctor can prescribe the same amount.
If we were using some other units this may not be the case. For example, british and american inch were different until 1950's.
Example: if you go to a surgery and a doctor needs to cut "1 inch from the left part" it may cause a mistake as this unit is different in different countries. But if he needs to cut "2.5 cm from the left part" he knows exactly where to cut.
Another benefit of using metric system is that it is being used in almost every country in the world.
Percentage of Lemonade = 100 - (15 + 5)
= 100 - 20 = 80%
Now, We have to calculate the 80% of total amount of the drink i.e., 300 ml
So, 300 * 80%
= 300 * 0.80 [ 80% = 0.80 ]
= 240
In short, Your Answer would be: 240 ml
Hope this helps!
