Answer:153.9 cm
Step-by-step explanation:
The area of a circle is found by pi × radius squared and pi is aprox 3.14 so 3.15×7² = 153.86 then round off to the nearest tenth you get 153.9
Answer:
Can not be determined.
Step-by-step explanation:
We can easily notice that the limit is x tends to infinity, whereas x is not present in the given function, we are given (1 + 1/n). So we can not evaluate the given limit for x as parameter, we must have some function of x to solve this problem.
Hence, option C is correct i.e. the limit can not be determined.

11. 6.9 < x - 2.3
+ 2.3 + 2.3
9.2 < x = x > 9.2
Hope this helps!
The arithmetic sequence with the given condition is determined recursively by

So we have



and so on with the general pattern

This means the 72nd term in the sequence is

so the answer is B.
