V solid = π *

* 13 / 3 + π *

* 2 = 3.14 * 25 *13 / 3 + 3.14 * 50 = 340.16 + 157 = 497.16 ≈ 497.20 cubic centimeters;
What kind of problems or what are you trying to ask?
I’m pretty sure this is how you do these kinds of questions, but I may be entirely wrong, so don’t 100% trust me on this one
Answer:
400 mm
Step-by-step explanation:
to convert cm to mm, you add a 0, or more specifically, multiply by 10. so, 15 × 10= 150. 250+150=400.
(x) + (x + 2) = 58
2x + 2 = 58
2x = 56
x = 28
The two numbers are 28 and 30.
Hope this helps!
