Answer:
The value of pi is equal to 3.14
It has a coefficient of 4 :)
Area of semicircle is given by:

r is the radius, and we are given the diameter. Radius is half the diameter, so it's 2.5m. Let's plug that into the formula (using 3.14 as an estimation for pi):

So, the area of this semicircle is
9.81m².
Answer:
.023------ 7/30
.4------ 4/9
1.6----- 5/3
3.5------ 32/9
All I did was divide each fraction (the numerator by the denominator) and use the answer I got to match the fraction with the decimal.
hope this helps!
All you have to do is 100 plus 10 is 110 plus if you need to understand it better you can use base ten blocks use one hundred block and 1 tens block is the same thing. 100 is in one block and 10 is in one tens block. Hope this helped you ( :
