A group of 169 students needs to be seated in a square formation for a

otez555 [7]

We have a group of 169 students that needs to be seated in a square formation. Then, the number of rows has to be the square root of 169 :-

$r = \sqrt{169} = 13$

Then, a square of 13 rows and 13 columns will fit the 169 students.

If the number of students is 1024, then the number of rows <em>N </em>can be calculated as :-

${N}^{2} = 1024$

$N = \sqrt{1024}$

$N = 32$

<h3><u>Final Answer :-</u></h3>

169 students will seat in a 13×13 formation.

1024 students will seat in a 32×32 formation (N=32)

Step-by-step explanation:

To find the area of the shaded region, find the area of the circle and divide it in 4. This will the area of the portion with the triangle.

Now, find the area of the triangle and subtract the two. The resulting value will be the area of the shaded region.

Circle:

$A = \pi r^2\\A = \pi 10^2\\A = 100 \pi\\A = 314$
