Answer:

11/7 feet

Step-by-step explanation:

the perimeter of a circle is πr²

and a semi circle is half of a circle then the formula would be 1/2 πr²

1/2×22/7×1 (it is 1 because we have divided the diameter to get radius

so we derived at 11/7

GarryVolchara [31]

Answer: (b)

Step-by-step explanation:

Given

The letter "BHUTAN" has to be arranged

For filing the first place of 6 letter word, we have 6 choices

Similarly for filling the second place of the word, we have 5 choices as 1 letter is already filled.

In this way, the remaining places can be filled in 4, 3, 2, and 1 way

On combining the above, 6 places can be filled in  

\Rightarrow 6\times 5\times 4\times 3\times 2\times 1=6!\\\Rightarrow 720\ \text{ways}

Thus, option (b) is correct.
