Who is my work I think the answer would be -190
Volume of oblique cylinder
= (base area) * height (perpendicular to base)
= (30 π )*m
= 30m π cm^3

Except for 2 and 5, all prime numbers end in the digit 1, 3, 7 or 9.
For number 13, there is no change. It is 0. The equation is x=7 since the line is on x and not y. The y intercept is 0.
The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h.
<span>A=<span><span>(<span>a+b</span>)</span>2</span>h</span>
Solve for a.
