Answer:
Perimeter of first triangle = 102.73
Perimeter of 2nd triangle = 123.27
Step-by-step explanation:
Dividing the area of two triangle we can find the square of the scale factor:
= 1.44
Scale factor will become = = 1.2
Sum of perimeter of triangle = 226dm
perimeter of triangle = x + y + z = p
perimeter of first triangle = 1.2(x + y + z) = 1.2p
perimeter of 2nd triangle = (x + y + z) = p
Permieter of first triangle + Perimeter of second triangle = 226
1.2(p) + p = 226
2.2p = 226
p = 102.73 // This is the perimeter of 2nd triangle
For finding permieter of first triangle, multiply it with 1.2
102.7 * 1.2 = 123.27 // This is the perimeter of 1st triangle
Answer:
1. cone
radius, height = 2, 10
volume = 13.33
2. hemisphere
radius= 14
volume = 1829.33
Step-by-step explanation:
The region described has a radius r=2−y/5, therefore, the volume is a cone
radius, height = 2, 10
volume =
= 13.33
2. The region ∫14 0 π(196 - h^2) dh has a radius 196 - h^2, so the volume is a hemisphere
radius = 14
volume
=
=
=1829.33
