What is the surface area of a right cylinder which has a base with radius 9 units and has a height of 12 units?

1187.52

Step-by-step explanation:

A=2πrh+2πr2=2·π·9·12+2·π·92≈1187.52202

1187.997

Step-by-step explanation:

surface area =2πrh+2πr^2

(2•22/7•9•12)+(2•22/7•9^2)

44/7(108)+44/7(81)

6.285(108)+6.285(81)

678.857+509.14

1187.997

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
