So the range is that combined sugar and chocolate chips you can have [1,10/3] cups.
So far, you have already poured in three and three quarters which in improper fractions is 15/4. Multiply the y-range of the combined with 4, to get this:
12/12 => 40/12. Then multiply 15/4 by three to get 45/12. Clearly you see this that more cups of sugar than the limit is poured. you can only go to 40/12, but 45/12 is just sugar, so no chocolate chips can be added
First, we find the diameter.
12.56 divided by 3.14 = 4.
Next, find the radius.
4 divided by 2 = 2.
Then, use the formula to calculate the area.
2 times 2 times 3.14 = 12.56 is your area.
In this case, the area and the circumference are the same. Sometimes that is not that case though. Hope it helps! :)
Answer:
Step-by-step explanation:
a² + b² = c²
or in the case of a square where a and b are identical
2a² = c²
a = √(c²/2)
a = √(30²/2)
a = √450
a = 21.213203...
a = 21 m
