The cylinder has a height of 30cm and radius 11cm. work out the total surface area of cylinder

total surface area=2832.66 cm^2

Step-by-step explanation:

11^2(3.14)x2=area of ends=760.26 cm^2

11x2x3.14=circumference=69.08 cm

69.08x30=area of side=2072.4 cm^2

2072.4+760.26=2832.66 cm^2

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
