Rose bushes are to be planted along edge of a circular flower garden of radius 3.2m at 5dm apart. How many bushes can be planted?

Sagot :

First, let's find the circumference if the circular garden.
C= 2πr
C= 2 × 3.14 × 3.2
C= 20.096 m

then translate it into decimeters, so it will be 200.96.
Divide it into 5.
200.96 × 5 = 40.192 remove the decimal places, and add 1 so 
the answer is 41

41 bushes can be planted.
