Answer:
d
Step-by-step explanation:
Volume can be described as the total amount of space that is in a closed surface. this amount of space is usually three dimensional. Volume is usually measured in m³ or cm³ or in³
For example,  the volume of a rectangular box given the following dimension : length - 3cm 
breadth - 8cm 
height - 10 cm 
volume = length x width x height = 8 x 3 x 10 = 240 cm³ 
 
        
             
        
        
        
Answer:
The value of cos Ф is ± 
Step-by-step explanation:
There are important rules for sin Ф and cos Ф
∵ sin Ф = 
∴ sin²Ф = 
∴ sin²Ф = 
→ By using the third rule above
∵ cos²Ф = 1 - sin²Ф
∴ cos²Ф = 1 - 
∴ cos²Ф = 
→ Take square root for both sides
∴ cos Ф = ± 
∴ The value of cos Ф is ±
