Answer:
see explanation
Step-by-step explanation:
A = πr² ← r is the radius and r = 
d ← d is the diameter
Hence
π ( d)² = A, that is
= A ( multiply both sides by 4 )
d²π = 4A ( divide both sides by π )
d² = 
( take the square root of both sides )
d = 
34.06 is the the correct way of saying it.
Answer:
-5 would Be your answer
Step-by-step explanation:
you would change the denominators to the least common multiple, in this case, 12. then you would change the fractions to 8/12, 14/12, and 7/12. you would add those, and get 29/12. divide 29 by 12, and get 2. add the rest to get 2 5/12.
