If by P=5ft you mean the radius is 5 then c = 2pi r or c = 10pi or approx 31.4 ft
Answer:
use the formula r = square root of (V / (pi x h))
Answer:
The value of b is, 8
Step-by-step explanation:
To determine the value of b:
Given:
....[1]
Since, 0x6A represents the hexadecimal form.
To convert this hexadecimal form into decimal form:

⇒
(decimal form)
Now we have to convert this decimal form into octal
8 | 106
8 | 13 | 2
| 1 | 5
1
Then, the octal form we get, 
Substitute this in [1] we have;

On comparing both sides we have;
b = 8
Therefore, the value of b is, 8
