Let x be the width of the playground, then 3x is the length of the
<span>playground
х * 3х = 75
3x</span>² = 75
x² = 25
x = 5 m (width)
5*3=15 m (length)
Perimeter = 2(5+15) = 2*20 = 40 meters.
Answer:
B) 195 m³
Step-by-step explanation:
The formula for the volume of a traingular prism is
V = (1/2)bhd where b is the base, h is the hieght, and d is the depth
the base and height come from the triangle side, the depth is the other measure.
Here, we have b = 6, h = 13, and d = 5
V = (1/2)(6)(13)(5)
V = (3)(13)(5)
V = 39(5)
V = 195 m³
Answer:
The answer to your question is Volume = 254.34 in³
Step-by-step explanation:
Data
diameter = 6 in
height = 3 radius
π = 3.14
Formula
Volume = πr²h
Process
1.- Calculate the radius
radius = diameter / 2
= 6/2
= 3 in
2.- Calculate the height
height = 3radius
height = 3(3)
= 9 in
3.- Calculate the volume
Volume = (3.14)(3)²(9)
-Simplification
Volume = (3.14)(9)(9)
-Result
Volume = 254.34 in³
Both of those angles are 45
Look up 90 45 45 triangle:)
