Answer:

V=5.30\ m^3

Step-by-step explanation:

we know that

The capacity of the pond is equal to the volume of a cylinder (circular pond)

V=\pi r^{2} h

where

h=750\ mm=75\ cm=0.75\ m ---> to convert mm to m divide by 1,000

r=1.5\ m

assume

\pi =3.14

substitute

V=(3.14)(1.5)^{2} (0.75)=5.30\ m^3

Solve 7r+ 2 = 5(r – 4) ​
AveGali [126]

Multiply the bracket by 5

I used PEMDAS

P= parenthesis

E= exponents

M=multiplication

D= division

A= addition

S= subtraction

7r+2= 5(r-4)

7r+2= 5r-20

Move 5r to the left hand side . Positive 5r changes to negative 5r

7r-5r+2= 5r-5r-20

2r+2=- 20

2r+2-2= -20-2

Move positive 2 to the right hand side. Changes to negative -2

2r+2-2= -20-2

2r= -22

Divide by 2 for 2r and -22

2r/2= -22/2

r= -11

Answer is r= -11
