30: x
60: xsqrt3
90: 2x (hypotenuse)
Answer:
The answer is A, 18.84.
Step-by-step explanation:
The two points are 6 places apart, so that can be 6 units as radius. To find the circumference of a circle you do r x 3.14 (to abbreviate pi). 6 x 3.14 is 18.84 so A is your answer.
You need to divide 122 by 10, then you multiply your answer by 10 and see if you get 122. So 122 divided by 10 = 12.2, then 10 x 12.2= 122.

sum is the same
Answer: 2*pi and √3.
Step-by-step explanation:
We know that when we multiply a rational number different than zero and an irrational number, the product will be also an irrational number.
Then if one of the numbers for this case is 7/3 (A rational number), the other must be an irrational number.
The given options are:
3/7 (is a rational number, so this is not the correct option)
2*pi (pi is an irrational number, then 2*pi is also an irrational number)
Then (2*pi)*3/7 will be an irrational number.
1 (this is a rational number, then this is not the correct option)
√3 (This is an irrational number, then this will be a correct option)
Then the two correct options are:
2*pi and √3.
