If the circumference of the circle is equal to 3.14 units, to find the area
The area of a circle can be calculated using the diameter or the radius with two different formulas: A = πr2 or A = π(d/2)2, where π is the mathematical constant approximately equal to 3.14,r is equal to the radius, and d is the diameter.

Answer:
(b) tan B = 8/6
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relevant relationships:
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
Then angle B is involved in tangent and cosine relationships this way:
tan B = 8/6 . . . . . . matches 2nd choice
cos B = 6/10 . . . . . matches no choices
_____
<em>Additional comment</em>
Both of the offered cosine choices give a cosine value that is greater than 1. The cosine of a real angle is never greater than 1, so those can be rejected immediately.
Answer:
12 months time
Step-by-step explanation:
To find this, we simply find the lowest common multiple of the two months
Mathematically, we have the lowest common multiple of 4 and 6 as 12
Thus, the time they would have the appointment together is the simply 12 months
