Answer:
r = 2cm
h= 18cm
surface area of cylinder = 2πr ( r + h)
= 2*22/7*2(2+18)
= 125.714cm²
volume of cylinder = πr²h
22/7*(2)²*18
=226.29cm³
4/3.2 = 7/x
4x = 22.4
/4
x = 5.6
N= 18
5/6=15/n you cross multiply them and you get 5n=90
Then you get the n by itself by doing 5n/5 and then you do the same to the other side by doing 90/5 and you get n=18
Answer:
90 games
Step-by-step explanation:
Given: Total number of team (n) = 10
Each team will play twice with each other.
We know that every team will play two game with each other except with itself, therefore each team will play 
⇒ Each team will play = 
∴ Each team will have 18 games with each other in the league.
Now, as there are total 10 teams and each team have 18 games each, however, we have to make sure that no team have more than two games with other team.
Example: 
Both the above game are same and it is a mistake to take two different game.
∴ Total number of games played by all team= 
⇒ Total games = 
∴ Rana have to schedule 90 games in the Volleyball league.
Answer:
11 sq.ft
Step-by-step explanation:
∅= 80×π/180= 4π/9
area= 1/2 × r²× ∅
= 1/2 × 16 × ∅
= 8∅
=8×(4π/9)
= 32π/9
= 11.17 ~11
