Answer:
Option (1). 142.4 cubic units
Step-by-step explanation:
The given question is incomplete: here is the complete question.
What is the volume of the oblique cone? Round to the nearest tenth.
142.4 cubic units
142.4 square units
196.0 cubic units
196.0 square units
Volume of n oblique cone is represented by the formula,
V =
From the figure attached,
Radius of the base = 4 units
Height of the cone = 8.5 units
Therefore, area of the base = πr²
= π(4)²
= 16π
Now volume of the cone =
= 142.4 cubic units
Therefore, Option (1) will be the answer.
Answer:
x=-8
Step-by-step explanation:
on squaring both sides
either x-2=0 or x+8=0
either x=2 or x=-8
Putting x=2 in original equation, we get
7=7 hence, it is not an extraneous solution
Putting x=-8 in original equation
i.e. 3=-3
Hence, x=-8 is an extraneous solution (since it doesn't satisfy the original equation)
