Answer:

178.07

Step-by-step explanation:

First you have to multiply 13 x 16 = 208. After that you have to find the area of the missing piece, to find that you have to add 5.7 + 6.2 = 11.9, and then subtract by 16 to get 4.1. Then you multiply 7.3 x 4.1 = 29.93.

29.93 is the area of the missing piece

So you would subtract the area of the whole thing (208) by the area of the piece (29.93)

To get the answer 178.07

svetlana [45]
C = 2<span>πr
C = 2 * 3.14 * 5.1
C = 32.028

You can round that to A. 32.03, because if the decimal after 2 is greater than it, then you round it to the number which is higher than it, which is 3. </span>

What is 1 5/8 +4 7/8 show work
Anon25 [30]
Take the mixed number apart and have a whole number and a fraction
1+4 and 5/8 + 7/8
1+4=5
5/8 + 7/8 = 12/8
12/8 = 1 4/8
Add 5 to 1 4/8 
5 + 1 4/8 = 6 4/8
1 5/8 + 4 7/8 = 6 4/8
In simplest term, the answer is also 6 1/2
-------------------------------------------------
Another way to solve it is by turning both 1 5/8 and 4 7/8 into improper fractions.
1 5/8 = 13/8
4 7/8 = 39/8
Add them.
13/8 + 39/8 = 52/8
Turn 52/8 into a mixed number.
52/8 = 6 4/8
Simplify it to get 6 1/2.
