For a school assembly student's sit in chairs that are arranged in 53 rows. there 12 chairs in each row . about how many students can be seated show how you estimated.

636 students can be seated

Step-by-step explanation:

Given :

For a school assembly student's sit in chairs that are arranged in 53 rows.

There 12 chairs in each row .

To Find : About how many students can be seated show how you estimated.

Solution:

No. of chairs in 1 row = 12

There are 53 rows

So, no. of chairs in 53 rows =

                                             =

So, 636 students can be seated

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
