**7.** The length of a circular curve is given by the formula:

Where: L = length of curve in centimeters (cm)

r = radius of curve in centimetres (cm)

θ = angle of curve in degrees (q)

π = constant = 3.142…..

(most calculators have a ‘π’ button, if possible use this instead of entering the rounded number given here)

a) Transpose the equation to make* r* the subject.

b) A student sitting in an exam finds themselves ‘clock watching’. The student estimates that the minute hand of the clock moves a distance of 20 cm round the face of the clock in 10 minutes.

Based on the student’s estimation, how long is the minute hand?

Hint: how many degrees (out of 360q) make up 10 minutes on a clock face?

**8.** a) Solve the following simultaneous equations using a method of your choice.

*y *= −2*x* + 3

−6*x* + 2*y* = 1
