Plug your input (m) into the equation given. Then complete you table.
Figure 1
Perimeter
3 * (1/2) * (6π) + (1/2) * (18π) = 18π cm
Area
3 * (1/2) * ((3 ^ 2) π) + (1/2) * ((9) ^ 2π) = 54π cm ^ 2
Figure 2
Perimeter
6 * (1/2) * (4π) + 2 * (4) = (12π + 8) cm
Area
3 * (4 * 4) = 48 cm ^ 2
Figure 3
Perimeter
2 * (1/2) * (6π) + (1/2) * (12π) + 2 * (6) = (12π + 12) cm
Area
2 * (6 * 6) + (1/2) * ((6) ^ 2π) = (18π + 72) cm ^ 2
The mean or better known as the average is all of the numbers combined and then divided by how many numbers there were. You should be able to find the mean of any set of numbers. There might be a mistake in the calculations some where.
Answer:
The plane travels at a speed of approximately 262.768 miles per hour.
Step-by-step explanation:
The absolute velocity of the plane () is the vectorial sum of vectors from engines () and wind flow (). All vectors are measured in miles per hour. That is:
(1)
Let suppose that both north and east semiaxes are positive.
If we know that and , then the resultant velocity of the plane is:
The resultant speed of the plane is determined by Pythagorean Theorem:
The plane travels at a speed of approximately 262.768 miles per hour.
