Answer:
2.8 in
Step-by-step explanation:
The volume of any shape is given as the product of base area and height. Therefore, V=Ah
Where A is cross sectional area, h is height
For a triangular, the cross sectional area is given by ½lw where l is length and w is width.
Now v=½lwh
Given that v=4 in³
4=½lwh
8=lwh
Considering the given choices, l can be 2.8 in
Answer: 82
Step-by-step explanation:
H=9(-3)^2+1
Simplify both sides of the equation.
h=81+1
81+1 =82
h=82
