Answer:
Height = 19mm.
Step-by-step explanation:
Area of a regular polygon = (A * P) / 2 where A = side / (2 * Tan (π / N)) where, N = Number of sides, A = Apothem, P = Perimeter.
Here A = 5, P = 5*12 = 60 so
Area of the base = (5 * 60) / 2 = 150 mm^2.
Volume = area base * height so
Height = volume / area of base
= 2850 / 150
= 19 mm.
The boundary line should be solid because it have a 'great/less than or equal to' sign
It can help them by concentrating like mind games and teaching them. Learning from their mistakes something like that. Like reading games that help you with your subjects.
