Answer:
The answer is C.
Step-by-step explanation:
Both temporary and permanent magnets have below common specifications:
-Repels or attracts other magnets
-Attracts iron objects
Therefore, choices <u>B</u> and <u>D</u> is wrong.
Maintaining magnetic properties in the presence of another magnet and made from magnetically hard ferromagnetic material are both specification of permanent magnets. Thus, A is also a wrong choice.
So the answer is C.
Answer:
V ≈ 263.9 units³
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = 
πr²h ( r is the radius and h the height )
Here r = 6 and h = 7 , then
V = π × 6² × 7
= π × 36 × 7
= π × 252
= 84 π
≈ 263.9 units³ ( to 1 dec. place )
When you multiplied 4 and 12, the answer is not 36.
