Step-by-step explanation:
By replacing the points in the current equation you can get true statements which are correspondent to answer A,B,D
The scale factor applied to the model is 8000. 8000 times one equals 8000
Well, they're both divisible by 2 (24 ÷ 2 = 12) (90 ÷ 2 = 45)
Answer:
If 
, the slang height of the cone is approximately 23.521 inches.
Step-by-step explanation:
The surface area of a cone (A) is given by this formula:
Where:
- Base radius of the cone, measured in inches.
- Slant height, measured in inches.
In addition, the slant height is calculated by means of the Pythagorean Theorem:
Where 
is the altitude of the cone, measured in inches. If , then:
And:
Given that 
, the following second-order polynomial is obtained:
Roots can be found by the Quadratic Formula:
As radius is a positive unit, the first root is the only solution that is physically reasonable. Hence, the slang height of the cone is approximately 23.521 inches.
