Answer:
<h2>A. 60 in³</h2>
Step-by-step explanation:
The formula of a volume of a cone:

r - radius
H - height
We have r = 1.9 in and H = 15 in. Substitute:


You can add 4/9.
A simple trick is to look at the numerator and denominator separately, if they're both perfect squares then you're good (4, 2^2, check. 9, 3^2, check.)
Solution:
<u>Given:</u>
<u>Solve the equation by isolating the variable.</u>
- => 18 = 2b
- => 2b/2 = 18/2
- => b = 9
The value of b is 9.
