Answer:
<h3>The height of the pyramid is 7 feet</h3>Step-by-step explanation:
Let h represent the height of the pyramid
Volume of a pyramid is given by
Volume of pyramid = 84ft³
To find the height of the pyramid we must first find the area of the base
Since it's a square pyramid it's base is a square
Area of a square = l²
where l is the length of one side
l = 6feet
Area = 6² = 36ft²
So we have
84 = 12h
Divide both sides by 12
<h3>h = 7 feet</h3>The height of the pyramid is 7 feet
Hope this helps you
Answer:
The correct option is, Exponential Decay, $23,914.85.
Step-by-step explanation:
A farmer buys a tractor for $50,000.
It is provided that the the tractor depreciates 10% per year.
The exponential function for decay is:
Here,
a = initial value
r = decay rate
t = time
Compute the value of the tractor in 7 years as follows:
Thus, the correct option is, Exponential Decay, $23,914.85.
It is given in the question that the solid is a cone with height of 16 units and radius of 7 units .
The formula of volume of cone is
To find the volume, we substitute the given values of r and h and use 3.14 for pi. That is
And that's the required volume of the cone .
