Answer:
acc to ques....perimeter of figure= 3a^2+15a+9
let missing dimension be x
= x+10a-2+a^2-7+5a=3a^2+15a+9
x+15a+a^2-9=3a^2+15a+9
x=2a^2+18
A circular concrete slab is a cylinder. Vol = pi%2Ar%5E2%2Ah
in this cylinder:
r = 18%2F2 = 9 ft
h = 3%2F12 = .25 ft
:
Find the volume in cu/ft:
V = pi%2A9%5E2%2A.25
V = 63.61725 cu/ft
:
Change to cubic yds; (1 cu/yd = 27 cu/ft) and multiply by $40:
Cost = 63.61725%2F27 * 40
Cost = $94.25
In practical terms , they may require you to buy 3 cu/yds , which is $120

Answer:To calculate the volume of a triangular prism, measure the width and height of a triangular base, then multiply the base by the height by 1/2 to determine the triangle's area. Next, measure the height of the triangular prism and multiply this by the triangle's area to get the volume. I hope that helped a little
