Answer:
The polygon is a concave polygon
The polygon is irregular polygon
Step-by-step explanation:
Convex polygon is polygon that has all interior angles less than 180°
In a convex polygon, every diagonal of the figure passes only through interior points of the polygon
A line drawn through a convex polygon will intersect the polygon in exactly two points
Some of convex polygons can be regular polygons
Concave polygon is a polygon that has one or more interior angles greater than 180°
In a concave polygon, at least one diagonal of the figure contains points that are exterior to the polygon
A line drawn through a concave polygon, can intersect the polygon in more than two points
Concave polygon never be a regular polygon
From the attached figure
∵ The polygon has one diagonal lies out the interior of the polygon
∴ The polygon is a concave polygon
∵ All the concave polygons are regular polygons
∴ The polygon is irregular polygon

Answer:
62.8 cubic inch
Step-by-step explanation:
For Cylinder
height (h) = 5 in
radius (r) = 2 in
Volume of Cylinder
= <em>π r² h</em>
= 22/7 * 2 * 2 * 5
= 22* 20/7
= 440/7
= 62.8 cubic inch
Thus, the volume of the cylinder is <em><u>62.8 cubic inch</u></em>
When we look at this thing for the first time, it looks like it's going to be a dog of a bear to solve, because 'q' is buried inside a squared term and a cubed term.
But this is why it's so important to learn that in math, you DON't immediately ignite your hair and go running around in circles as soon as you see the problem. The first thing you have to do <u>every</u> time is sit still, look at the problem, breathe air, and switch your brain into the 'ON' position.
Look at that big ugly fraction in the equation. Can it be simplified ? You betcha it can ! The quantity (q+r) is a factor of the numerator and denominator, so we can do some canceling.
Divide the top and the bottom of the fraction by (q+r)², and then the problem says . . .
<em>p = (q+r)/12 + 4r</em>
which is MUCH easier to unravel and solve for 'q' . Let's do this !
p = (q+r)/12 + 4r
Subtract (q+r)/12 from each side . . . p - (q+r)/12 = 4r
Subtract 'p' from each side . . . -(q+r)/12 = 4r - p
Multiply each side by -1 . . . (q+r)/12 = p - 4r
Multiply each side by 12 . . . (q+r) = 12p - 48r
Subtract 'r' from each side . . . <em>q = 12p - 49r</em>
