Answer:
see below
Step-by-step explanation:
Because the area of the square is 36 its side is 6 meaning the circle has a diameter of 6. This means that its radius is 3 so its area is 3² * π = 9π.
A vector has length (magnitude) and direction.
Multiplying a vector by a scalar can alter both its length and its direction.
Specifically, you are multiplying by
.
When you multiply a vector by a negative as in this case the direction changes.
Next when we multiply by a quantity greater than 1 the vector's length increases. When we multiply by a quantity less than 1 the vector's length decreases. Here you are multiplying by a quantity less than 1. For the sake of getting an estimate pi is approximately 3.14 so dividing that by 4 gives you a quantity less than 1.
So multiplying by
will have the following effects on the vector:
It will face the opposite direction and it will be shorter (have less magnitude). Specifically the magnitude will be
of what it was before.
On A, your goal is to find the distance from each sibling from their home. First, take 280 x 6 to find Dante’s distance. Then, take 450 x 6 to find Shawn’s distance. Write the two factors down labeling Shawn’s distance from Dante’s. To find B, then take 832” divided by 280, they want to know the amount of time. Remember, if you end up with a decimal, round to the nearest tenth or hundredth for the exact answer.
On C, take 11,680 divided by 280 and 11,680 divided by 450, the. Subtract Shawn’s minutes from Dante’s minutes to find the answer. The graph really isn’t needed to answer that question.
Answer:
A = pi (15)^2
Step-by-step explanation:
The diameter is 30
The radius is 1/2 of the diameter
r = d/2 =30/2 = 15
The area of a circle is
A = pi r^2
A = pi (15)^2
A = 225 pi
