On a map the length of a lake is 4.5 centimetres. The actual length of the lake is 2.7 kilometres. Write the scale of the map as a ratio in the form 1 : n.

1:60000

Step-by-step explanation:

Make sure the units match by converting 2.7km to 2700000cm. Divide 2700000 by 4.5 to get 60000. So, every 1cm on the map is 60000cm in real life

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
