Answer:
Volume of the rock=
Step-by-step explanation:
Volume of triangular pyramid = 
Where B is the area of base
H is the height of pyramid
Length if base of base triangle = 8.5 inches
Height of base = 4 inches
Area of base triangle = 
Height of pyramid = 12 inches
Volume of triangular pyramid = 
So, option D is true
Volume of the rock=
Answer:
q=-14
Step-by-step explanation:
Answer: The area is 5024 yrd^2
Step-by-step explanation:
80 is the diameter to we need to divide it by 2 to find the radius
80/2= 40
A= 3.14* 40^2
A = 3.14 * 1600
A= 5024
Answer:
B. 1,188 cubic units
Step-by-step explanation:
First find the area of the base
A = 1/2b*h (this would only be half the base so our formula would be)
A = b*h (Now enter values)
A = (9)(6)
A = 54 (now plug this into the volume formula)
V = Ab * h
V = (54)(22)
V = 1,188 cubic units
