In a equilateral triangle, all sides are equal.
hence each slant side = 12cm
to find the height of the triangle :
use Pythagoras’ Theorem (A^2 + B^2 = C^2)
A = height
B = 6
C = 12
A^2 = 108
A = 10.392... (5s.f.)
area = ½ x base x height
= ½ x 6 x 10.392...
= 31.176
= 31.2 (3s.f.)
Answer:
The volume of diamond is 20 cubic inches.
Step-by-step explanation:
We are given the following in the question:
Triangular base:
Base = 4 inches
Height = 5 inches
Height of the pyramid = 6 inches
Area of triangular base =
Volume of diamond = Volume of pyramid
Thus, the volume of diamond is 20 cubic inches.

Step-by-step explanation:
Answer:
We have the system:
y > 2*x
y > 3
Now, let's find the limits:
taking y > 3, we can see the limit y = 3.
Now we replace it in the first inequality:
3 > 2*x
3/2 > x.
Then we have that:
y > 3
x < 3/2
Those two inequalities define our system.
So any ordered pair where x is smaller than 3/2 and y is larger than 3, is a solution.
or example:
(1, 3.5) is a solution.
