Answer:
4 and -6
Step-by-step explanation:
The answer is 120.1 in
The volume of the cylinder (V1) is
V1 = π · r² · h (r - radius, h - height)
The volume of the storage tank (V) is the volume of 25 cylindrical containers:
V = 25 · V1 = 25 · π · r² · h
It is known:
V = 115500 in³
π = 3.14
r = 3.5 in
h = ?
V = 25 · π · r² · h
⇒ 115500 = 25 · 3.14 · 3.5² · h
115500 = 961.625 · h
⇒ h = 115500 ÷ 961.625 = 120.1 in
(x^2 + 5x - 6)/(x^2 + 9x + 18)
= (x - 1)(x + 6)/(x + 3)(x + 6)
= (x - 1)/(x + 3)
The area of each triangle face is 5.25 unit.
<h3>What is an
area?</h3>
Area is the amount of space occupied by a two dimensional object or figure.
For triangular pyramid:
Surface area = sum of the area of the three triangle.
The salt lamp is a triangular pyramid with equal triangles, hence:
Surface area = 3 * area of each triangle
15.75 = 3 * area of each triangle
area of each triangle = 5.25
The area of each triangle face is 5.25 unit.
