I believe that cheating is not tolerated at whichever school that you attend.

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.

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

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
