Answer:5.8
Step-by-step explanation:
Given
weight of chair with person on it =2118 N
Barber applies a force of 63 N
Using pascal's law
we know pressure around both sides is equal
i.e. 
pressure=
=
=
substituting values
![\left [\frac{r_{plunger}^2}{r_{piston}^2}\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7Br_%7Bplunger%7D%5E2%7D%7Br_%7Bpiston%7D%5E2%7D%5Cright%20%5D)
=

4 5/2 is 6 1/2 in simplest form!
Answer:
43.25
Step-by-step explanation:
We have two flower beds in this example, the first has a perimeter of 100 feet, and the second has a perimeter of 180 feet
The total is 280 feet
<h3>Perimeter of Rectangle</h3>
Given Data
Dimension of the first flower bed
Length = 17 feet
Width = 33 feet
Perimeter = 2L + 2W
Perimeter = 2*17 + 2*33
Perimeter = 34 + 66
Perimeter = 100 feet
Dimension of the second flower bed
Length = 40 feet
Width = 50 feet
Perimeter = 2L + 2W
Perimeter = 2*40 + 2*50
Perimeter = 80 + 100
Perimeter = 180 feet
The total length will be 100+180 = 280 feet
