Answer: 2730 tiles (Approx)
Step-by-step explanation:
Since, The side length of each side = 25
According to the question the shape of the tile is square.
Thus, the area of one tile = 25 × 25 = 625 
Also, we need to tile a kitchen measuring 102 ft. by 18 ft
Thus, the area of the room in which we have to tile = 102 × 18 = 1836 
= 1836×30.48 × 30.48 = 1705699.8144
Thus, the total number of the tiles = the area of the room in which we have to tile / the area of one tile = 
Since, we must take 2730 tiles to tile the kitchen.
Area = pi*r^2
Circumference = 2pi*r
Step 1: find the radius from area
81pi=pi*r^2
81=r^2
9=r
Step 2: plug in radius to the circumference equation
Circumference = 2pi*r
18pi is the answer, otherwise know as 56.52 as well.
Answer:
13
Step-by-step explanation:
The computation of the number of people in the chorus are 50 or older is as follows
According to the attached figure
In the age of 50 - 60 , there is 8 people
In the age of 60 - 70 , there is 4 people
In the age of 70 -80, there is 1 people
So, if we do the total that comes
= 8 people + 4 people + 1 people
= 13 people
Hence, the no of people would be 13
The same is relevant
