Answer:

4.46

Step-by-step explanation:

The formula for diameter (Yes, diameter, stick with me here.) is d = c/π. Plug in your circumference; d = 28/π, which equals 8.912676813 rounded to the nearest billionth. The formula for radius is d/2. So, 8.91267813/2 is 4.456338407 (rounded to the nearest billionth) generally, you are supposed to round to the nearest hundredth. Unless the question says otherwise, the 6 rounds the 5 up, leaving you with 4.46 as the final answer.

How do I solve 9a-7=110

Sphinxa [80]

You'll need to isolate 9a on the left side of this equation
Please add 7 to both sides of the eqn, obtaining 9a = 117.

Solve for a by dividing both sides by 9: a = 117/9 = 13 (answer)
