Answer:
AB = AC = 6 cm
AD = 6*2 = 12 cm
Step-by-step explanation:
Solution:-
- A small sketch of a right angle triangular base pyramid could help use visualize the right angle triangle base ( A B C )
Where Length,
AB = AC = x
AD = 2*AB = 2x
Where, The point D directly above A.
- The volum ( V ) of a pyramid is given by:
V = [ Base Area * h ] / 3
- Where, Base Area : The area of triangle ABC
h : The total height of the pyramid, AD
- The base area of the triangular base ( A B C ) is given by:
Base area = 0.5*AB*AC
= 0.5*x*x
= 0.5x^2
- The height of the pyramid, AD = 2*AB = 2*x
- Compute the value of x, for the given volume V = 72 cm^3:
3*V = 0.5x^2* 2x
3*72 = x^3
216 = x^3
x = 6 cm
Answer:
Step-by-step explanation:
Given formula to find the area:
Find radius first:
The circumference in this situation would be 38 feet.
Since we need to find radius, do division to 38 by 6.28.
Our radius is 6.05
Now back to the original formula which is:
Substitute:
2/10 because 0.7/7 is equal to one tenth, so 1.4/7 is equal to 2/10
Here is your answer in the format of a PNG file.
The last would be a < 40 if you'd be going under $40.
