<span>Sister is 5 </span>
<span>Yan Ling is 9 </span>
<span>9+5=14 </span>
<span>1 less than twice 5 is 9.</span>
We know that circumference = diameter * 3.14, so in order to find the diameter all we have to do is:
circumference/3.14 = diameter
So, we can plug in the value of the circumference:
34 / 3.14 = 10.82
The exact answer is 10.82.
The approximate answer is 11.
a. 9 cm 2 because each side would be 3 and length x width would be 3 x 3 = 9
