6. a) An aeroplane flies 60 km from A to B in the bearing of 070° and then 90 km from B to C in the bearing of 105°. Represent this information by drawing in a scale
of 1 cm = 10 km and answer the following questions.
(ii) What is the bearing of C from A?
(i) How far is C from A?
(iii) What is the bearing of A from C?​

If gravity is one third on mars then weight also one third on mars

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
