A regular pentagonal prism has a volume of 2,850 cubic millimeters. what is the height of the prism? a regular pentagonal prism

zlopas [31]

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.

Answer:

A. 3x^2 + 4 = 52

3x^2 = 52 - 4

3x^2 = 48

x^2 = 48/3

x^2 = 16

x = $\sqrt{16}$

x = 4

B. x^2 - 121 = 0

x^2 = 121

x = $\sqrt{121}$

x = 11

C. (b + 4 )2 = 49

2b + 8 = 49

2b = 49 - 8

2b = 41

b = 41/2
