Answer:

The perimeter of the semi circle is gonna be π or 3.14

Step-by-step explanation:

The diameter is 2 so that basically also means the main circle diameter is also 2

we trying to find it’s circumference (perimeter)

We can follow the equation

C=πd

In this case d is 2

So 2π

And since that is full circle, half circle would be π

Ainat [17]

Answer:

450m South

Step-by-step explanation:

Total distance traveled Northward :

1000m + 600m = 1600m Northward

Total distance traveled Southward :

1250m + 800m = 2050m

The Displacement :

Southward - Northward

2050m - 1650m

= 450m

Since, it covers more distance towards the south, then, direction is southward

450m South
