Question 1
A = π r ²
A = π x 65 x 65 m ²
A = 13273 m ²
Question 2
3 figure bearings are measured clockwise from North.
Answer is WEST
Question 3
1.852 km<--->1 nautical mile
3704 km<---->(3704 / 1.852) nautical miles
= 2000 nautical miles.

1) pi*65^2 = 13273 metres squared
2) 270 degrees = West (because 0 degees is north)
3) 3704/1.852 = 2000 nautical miles

1) area = Pi x r^2
A = 3.14 x (65)^2
= 13266.5
=13267 m^2
2) 0 deg is North, 90 deg is East, 180 deg is South and 270 deg is West
3) I nm = 1.852 km
3704 km = 3704/1.852 nm
= 2000 nautical miles

area of circle = pi r^2
= 3.1415 * 65^2
=13272.8375 m sq
name for 270 deg will be SOUTH.
1 km = 5.39957 nm
3704 km = 2000 n m
