Use Pythagorean Theorem:
a² + b² = c²
"a" is one side of the right triangle.
Its length is: radius of larger circle minus radius of smaller circle: (11 - 3 = 8)
The distance between the center of the circles creates the hypotenuse (17)
8² + b² = 17²
b² = 225
b = 15
Answer: the length of the common external tangent is 15.

Answer:
= 3,000,000,000
Step-by-step explanation:
Step 1- Multiply
5×6= 30
Once you've multiplied, you can just add the 0's to 30.
There are a total of eight 0's.
Once you've added all the 0's, you'll get 3,000,000,000.
