Surface Area of cylinder = 8195.4 inches^2

Step-by-step explanation:

we are given:

Diameter of cylinder = 30 inches

Height of cylinder = 72 inches

We need to find:

Surface area of cylinder = ?

The formula used is:

Surface\,\,Area=2\pi rh+2\pi r^2

We know radius = diameter/2

so, radius = 30/2 = 15 inches

putting values:

Surface\,\,Area=2\pi rh+2\pi r^2\\Surface\,\,Area=2*3.14*15*72+2*3.14*(15)^2\\Surface\,\,Area=6782.4+1413\\Surface\,\,Area=8195.4

So, Surface Area of cylinder = 8195.4 inches^2

Find the exact solution of the system of equations of x^2+y^2-4x-6y+4=0 and x^2-4x-3y+4=0
gavmur [86]
We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0 
                                                              y^2-3y=0
                                                             y(y-3)=0
                                                               y1=0 -----------y2=3
