Answer: See below
Step-by-step explanation:
Radius of the semicircle = 46/2 = 23 m

So, Val might have have subtracted 2116 from 3322.12 instead of adding since 3322.12 - 2116 = 1206.12
Ok so, when working to find if a fraction is equal to another you must know what it is cut down by. So 6 / 2 = 3. Now let's break down 7 by 2. It is 3.5 that is not four. So no 6/7 so not equal to 3/4.
6z - z^6
Since we don't have the value for z, we cannot solve the expression, however, we can get out most simple expression.
Answer: 5z^6
