Answer:

7.065 sq. cm

Step-by-step explanation:

Diameter= 3 cm

Since 2r=d, the radius is 1.5 cm

Circle area formula:

Plug in r:

A=3.14(1.5^2)

A=3.14(2.25)

A=7.065

1) How many 3/4 does it take to make 9/2?


     Now look at this, 3/4 x 6 = 4 1/2.  4 1/2 is the same as 9/2


   3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 ---> takes 6, 3/4's to make 9/2

2)  How many 3/4's go into 9/2?


    This is the same question as the 1st one so the answer is 6 :)


3)  9/2 divided by 3/4 = ??


         Use the KEEP< CHANGE< FLIP method, so it turns into  I
                                                                                                    I
                                                                                                    I
                                                                                                    I
      9/2 x 4/3                       < -------------------------------------          I


  This is equal to 36/6 which is 6 :)


The answer is 6 for numbers 1, 2, and 3 :)
