To find volume, we will use the following equation: V=4/3piR^3
The correct answer should be 1436.76
Answer:
A. cos 60° = ; x = 6 feet
Step-by-step explanation:
apex
Answer:
y = -3x - 5
Step-by-step explanation:
-2y = 6x + 10
divide both sides by -2
y = -3x - 5
Answer:
25π
Step-by-step explanation:
formula is pi*r^2
radius is half of diameter sooo
π*5^2 so 25π
hope this helped and

The dot product is used to determine the magnitude of the resultant vector of two component vectors. It is expressed as a·b. It does not literally mean that you multiply their values. Instead, you multiply their matrices. However, since we cannot find matrices, let's just find the resultant vector through theorems involving triangles. By cosine law:
R = √[a² + b² - 2abcos(3π/4)]
R = √[60² + 30² - 2*60*30*cos(3π/4)]
R = 83.94
Thus, a·b = 83.94
