The answer is
56/0.04=1400
Answer:
66 in
Explanation:
the circumference can be calculated as:

Where d is the diameter and π is 22/7.
So, replacing the values, we get:

Therefore, the circumference is 66 in.
The correct answer is:
[C]: "
a = ±
" .

___________________________________________________________Explanation: _________________________________________________________We are given:
_________________________________________________________ </span>
→ "
25 = a² + b² " ; Solve for "
a" ;
_________________________________________________________ → To solve for "
a" ; we want to isolate "
a" on one side of the equation.
_________________________________________________________We can rewrite: "
25 = a² + b² " ;
as: " a² + b² = 25 " .
_________________________________________________________
Then, we can subtract "
b² " from each side of the equation; as follows:
_________________________________________________________
→ " a² + b² − b² = 25 − b² " ;
to get:
_________________________________________________________ → " a² = 25 − b² " ;
_________________________________________________________ → Now, take the square root of EACH SIDE of the equation ;
to isolate "
a" on one side of the equation; & to solve for the value(s) of "
a" ;
_________________________________________________________ → √(a²) =

;
to get:
_____________________________________________________ → a = |
| ;
→ a = ±
;
→ which is:
Answer choice: [C]: "
a = ±
" .
