(3n-2m) (3n-2m)

(you multiply the first number (3n) by the first number in the 2nd bracket (3n) and then by the second number in the 2nd bracket (-2m)), and you do the same for -2m

9n2 - 6mn -6nm +4m2

9n2 -12mn + 4m2

Hi!

(3n - 2m)^2 = 9n^2 - 12mn + 4n^2

The correct answer is D. 9n^2 - 12mn + 4n^2

Hope this helps!

The height of the cylinder is 18 meters and the volume of the cylinder is 4,374 cubic meters. What is the area of the base of th
Mrac [35]

Answer:

242.76m^2

Step-by-step explanation:

Given data

Height=18m

Volume=4,374m^3

We know that the expression for the volume of a cylinder is

V=πr^2h

substitute

4374=3.142*r^2*18

4374=56.556*r^2

4374/56.556=r^2

77.339=r^2

r=√77.339

r= 8.79m

But the area of a circle is expressed as

A= πr^2

A=3.142*8.79^2

A=3.142*77.2641

A=242.76m^2

Hence the area of the base is 242.76m^2
