So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle.
Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.
I did one of them for you hopefully you can use my work for "a" to help you solve for "b".
For a. I got x=7.
Answer:
a₁ = 1; r = 3
Step-by-step explanation:
a₁ represents the first term. It is 1 in this case.
r represents the common ratio between terms. In this case it's 3 / 1 = 3.
Answer:
V≈340.34
Step-by-step explanation:
V=πr2h
3=π·52·13
3≈340.3392
The correct answer is: [B]: " 2.45 * 10⁵ " .

<u>Note</u>:
7 * 3.5 = 24.5 ;
24.5 * 10⁴ = 2.45 * 10⁵ .
