Answer:
Step-by-step explanation:
To isolate <em>a</em>, we add -3.75 to both sides.
<em>a</em>-(-3.75)=6.11
<em>a</em>-(-3.75)<u><em>+(-3.75)</em></u>=6.11<u><em>+(-3.75)</em></u>
<em>a</em>=6.11<em><u>+(-3.75)</u></em> Simplifying, we get:
<em>a</em>=2.36

The diameter is equal to 12.
Four as zeros don't count when you're figuring out significant figures
Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.
It’s a because you have to calculate and do the formal slope
