i need help!
it says you need working out as well so put that in please!!
a wheel measures 100cm with each complete rotation what is the diameter of the wheel?
there is a wheel with 30cm radius what is the circumference? the wheel makes 64 rotations calculate the length to the nearest metre
a wheel has diameter of 90cm the wheel goes all the way around once how far has it moved?

a wheel measures 100cm with each complete rotation what is the diameter of the wheel? 100/π = 31.83098862cm
there is a wheel with 30cm radius what is the circumference? 2π(30) = 60π = 188.4955592cm
the wheel makes 64 rotations calculate the length to the nearest metre 64(60π) = 3840π = 12063.71579cm = 120.6371579m
121 metres
a wheel has diameter of 90cm the wheel goes all the way around once how far has it moved? 2π(90) = 180π = 565.4866776cm

I made an error on last question it's meant to be
π(90) = 282.7433388cm
I mistook it for a radius.

oh god someone helped uhm theres more
a wheel has the diameter of 45cm how many times does it have to go around until it gets the same distance as the one with 90 diameter
a circle has the radius of 12cm whats the area
a circle has circumference of 120cm whats the radius
the area of a circle in square cm is 16pi whats the radius?

thanks a lot! still more
a tin has diameter 6cm and height 8cm the label that wraps around the tin is removed and laid flat what's the area of the label
a circle is drawn inside a square the circle touches the edges of the square the circles inside the square the square has sides of length 10cm what fraction of the square does the circle cover
2 more after this. |

a wheel has the diameter of 45cm how many times does it have to go around until it gets the same distance as the one with 90 diameter 90π/45π = 2
a circle has the radius of 12cm whats the area π(12)^2 = 144π = 452.3893421cm^2
a circle has circumference of 120cm whats the radius 120/2π = 19.09859317cm
the area of a circle in square cm is 16pi whats the radius? 16π/π = 16 √16 = 4

the best way to cheat on your math homework is to read how you do the math problem in the textbook
works every time
