It's 8 because the number in front of the variable is the slope, while the past 30 is the y intercept
Answer:
h = 9
Step-by-step explanation:
cylinder A = 
*4 = 113.0973355 
Cylinder B = 113.0973355 
113.0973355
= 
*h
113.0973355
/ 4
= h
8.999999999998 = h
I think b/c of the rounding error of rounding off pi, that h= 9
Option A:
m∠B = 42.1°
Solution:
Given data:
b = 18, c = 15 and m∠C = 34°
Using sine formula:

Substitute the given values.

Do cross multiplication.

Divide by 15 on both sides.





Switch the sides.
m∠B = 42.1°
Option A is the correct answer.
The length would be 9.
Area of a square is side^2, so to solve for side, take the square root of 81
