Answers

  1. The approximate value of 九十√70 is 11.51, correct option is 11.51.

    What is an approximation?

    An approximation is anything that is similar, but not exactly equal, to something else.
    Now, the value of 九 is given as 22/7 is 3.142
    To the nearest hundredth, it can be written as 3.14
    The value of +√70 is given as 8.366
    To the nearest hundredth as 8.37
    For the required value of the expression we can write,
    九十√70
    Put the value of 九 = 3.14
    and value of √70 = 8.37
    Putting values in expression we have,
    九十√70 = 3.14 + 8.37
    ⇒九十√70 = 11.51
    Hence,the approximate value of 九十√70 is 11.51.
    So,the correct option is 11.51.
