The diagram shows the entrance to a tunnel. The circular arc has a radius of 3 m and centre 0.
AB is horizontal and angle AOB = 120°.
a) Calculate the shaded area

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

step-by-step explanation:

8 2/3 is the answer

step-by-step explanation: just use a calculator

it is impossible.
