Answer:
1. 201.06 m
2. 1963.5 dm
3. 4536.46 mm
4. 17671.46 in
5. 254.47 cm
Step-by-step explanation:
You just have to plug these numbers into the formula for area of a circle.
The answer is 4 . 2 + 2 = 4 . hope i helped uuuu lol
You would do 5 times 4 which is 20. then count how many zero's there are and put them after the 20.
Given :
A particle moves in the xy plane starting from time = 0 second and position (1m, 2m) with a velocity of v=2i-4tj .
To Find :
A. The vector position of the particle at any time t .
B. The acceleration of the particle at any time t .
Solution :
A )
Position of vector v is given by :

B )
Acceleration a is given by :

Hence , this is the required solution .
Answer
Sol: The correct answer is b. three planes that contain point B are ABD, AEF and DHF.
