The second one if im not wrong
The fraction of a circle represented by the shaded region is:
S '/ S = ((8/5) * pi * r) / (2 * pi * r)
Rewriting we have:
S '/ S = ((8/5)) / (2)
S '/ S = 8/10
S '/ S = 4/5
Then, we can make the following rule of three:
(64/5) pi -------> 4/5
x ----------------> 1
Clearing x we have:
x = ((1) / (4/5)) * ((64/5) pi)
Rewriting:
x = (5/4) * ((64/5) pi)
x = (5/4) * ((64/5) pi)
x = 50.24
Answer:
The area of the complete circle is:
x = 50.24
4/9 divided by 2/3 divided by 5/6 = 4/5
when you divided by two fractions, you can flip the denominator and numerator and then mutiply
C - 3 1/12
Get a common denominator
3*3 / 4*3 + 1*4 / 3*4
Simplifies into 9/12 + 4/12
Adds to 13/12.
12 goes into 13 1 time, leaving us with 1 1/12
Add the 1 to the 2 full cups that already existed in the original problem - 3 1/12
