Step-by-step explanation:
Surface area of a cylinder:
2πrh + 2πr²
2π(5)(9) + 2π(5²)
90π + 50π
140π
For the answer to the question above, just <span>use similar triangles.
</span>Here's the equations that I used.
<span>t/h = (x + t) / r </span>
<span>x + t = rt / h </span>
<span>x = rt / h - t
I hope my answer helped you in your problem, Have a nice day</span>
Solving for s, I get s = 12.
Answer:
Step-by-step explanation:
<u>Direct variation equation:</u>
- y = kx, where k is constant of variation
<u>Given:</u>
<u>The equation is:</u>
<u>Find the value of x when y = 168:</u>
- 168 = 12x
- x = 168/12
- x = 14
The answer is A I believe
