Answer:

The number of ways the representative can be seated are:

720

Step-by-step explanation:

We know that when 'n' people are to be seated around a round table than the number of ways of doing so is calculated by:

                                                (n-1)!

Since in a circular seating there is no condition of the end point and hence the arrangement may start from anywhere.

Here we are given 7 nations who are to be seated at a round table.

Hence, the number of ways of doing so is:

(7-1)!=6!\\\\=6\times 5\times 4\times 3\times 2\times 1\\\\=720

          Hence, the number of ways to do so is:

                         720

Help me please for brainliest!
UkoKoshka [18]

Answer:

1)option b

2)option a

Step-by-step explanation:

1) circumference = 62.8 in

=> 2πr= 62.8

=> r= 62.8/(2×3.14)= 10 in

diameter = 2×10 in = 20 in

2)diameter = 14m

radius = 7 m

Area of the circle= πr² =3.14(7)²=3.14×49

= 153.86

=153.9 m²
