Step-by-step explanation:
100 as a product of its prime factors:


1) 0.927184
2) 0.615661
3) 0.383864
The diameter of the table is 42 inches. The radius of the table is half of the diameter of the table, so the radius of the table is 42/2 = 21 inches.
Add on 8 inches to the table radius to get: 21+8 = 29
So the radius of the table cloth is r = 29
Plug this into the area of a circle formula
A = pi*r^2
A = pi*29^2
A = pi*841
A = 841pi
A = 841*3.14
A = 2640.74
The approximate area of the table cloth is 2640.74 square inches.
3 people know a fact in 1st day.
In 2nd day they share it with 3 people each=3×3
Now 3×3 people shares it with 3 people each. and so on...
So,
3+3²+3³+3⁴+3^5+3^6+3^7
=3279 no of people altogether , will hear from 1st day to 7th day...
On the day 7,no of people who will hear the fact=3^7=2187
