The approximate value of 九十√70 is 11.51, correct option is 11.51.
<h3>What is an approximation?</h3>
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.
