Answer:
The area of the cube is 486 inches^2
Step-by-step explanation:
In this question, we are tasked with calculating the area of cube with side 9 inch.
Mathematically, the area can be calculated using the formula A = 6s^2
Now, what we need to do is to substitute 9 inches for s
Thus, A = 6 * 9^2
A = 6 * 81
A = 486 inches^2
You have to translate the statement into a mathematical expression...
Six times the number of cattle, if we let c be the number of cattle is:
6c
Less 87 means to subtract 87 so
6c-87
is 999 means
=999
so all together we have:
6c-87=999 now we need to isolate the variable by itself on one side of the equal sign....
6c-87=999 add 87 to both sides
6c=1086 divide both sides by 6
c=181
So there are 181 cattle.
Answer:
Step-by-step explanation:
tan is defined as: 
sin is defined as: 
cos is defined as: 
We can also define tan as: 
because plugging in the definitions of sin and cos in we get: 
which you'll notice is the original definition of tan(x)
So using this definition of tan(x) we can use the givens sin(x) and cos(x) to find tan(x)
plugging in sin(x) and cos(x) we get:
We usually don't like square roots in the denominator, and from here we want to rationalize the denominator which we do by removing the square root from the denominator.
We can do this by multiplying the fraction by: 
which doesn't change the value of the fraction since it simplifies to 1, but it gets rid of the square root in the denominator
Answer:
34072.3 in³
Step-by-step explanation:
Step 1
The circumference of its base is 125.6 inches.
C= pi x diameter
Find the radius of the base
C/ π = Diameter
Diameter = 125.6 in/2
= 62.8 in
Step 2
The height of the cone is 33 inches.
Radius = Diameter/2
Radius = 62.8 in/2
= 31.4 in
Volume of a cone: V = (1/3)πr²h
= 1/3 × π × (31.4)² × 33
= 34072.33162 in³
Approximately = 34072.3 in³
Therefore, the volume of Nuala's cone is 34072.3 in³.
