<span>When a </span>radius<span> is drawn to a point of tangency, the </span>angle formed<span> is always a right angle.
Basically, the 2 tangents and the radii form a quadrilateral.
The 3 angles on the right are 90, 111 and 90 degrees.
Therefore, the fourth angle = 360 -90 -111 -90
Which equals 69 degrees.

Formula for the area of a circle:
A = πr² (A = Area π(pi) r = radius)
You know:
r = 14 inches So substitute/plug it into the equation
[Radius is
(half) of the diameter. The diameter is 28, so half of 28 = 14]
A = πr² Plug in 14 into "r" since r = 14
A = π(14)² Find 14² --> 14 x 14 = 196
A = 196π in² Your answer is the 4th option
Answer:
The answer is $86 in all.
Step-by-step explanation:
What you first do is make the problem into a equation which would be
($25 + $25) + ($16 + $16)
or if you are at a more advance level it would be
2($25 + $16)
in word form it would be , add $25 and $16 two times for a total of $86 in total.
Answer:
There are 3 common factors of 8 and 20, that are 1, 2, and 4. Therefore, the greatest common factor of 8 and 20 is 4.
