Step-by-step explanation:
you know how to calculate the area of a rectangle ?
it is length × width.
now the volume of a 3D-rectangle (= a rectangular prism) is simply
length × width × height.
in our case
5 1/2 × 1 1/2 × 2 = 11/2 × 3/2 × 2 = 33/2 =
= 16 1/2 cubic units
Answer:
C
Step-by-step explanation:
(-3) x 4 = (-12) + 6 = -6
3 + 3 = 6 + (-12) = -6
(-6) = (-6)
Because adding positive to negative is like subtracting the negative if that makes sense.
Hope this helps!
Have a great day!

Answer:
C) 314 feet.
Step-by-step explanation:
We have been given that a circular track is 100 feet across. We are asked to find the distance around the track.
The distance around the track would be equal to circumference of circle.
, where r represents radius of circle.
Since we have been given across distance, so it will be diameter of track.
To find radius we will divide across distance by 2.
![r=\frac{100\text{ ft}}{2}=50\text{ ft}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B100%5Ctext%7B%20ft%7D%7D%7B2%7D%3D50%5Ctext%7B%20ft%7D)
Upon substituting our given values in circumference formula, we will get:
![\text{Circumference of circle}=2\times 3.14\times 50\text{ ft}](https://tex.z-dn.net/?f=%5Ctext%7BCircumference%20of%20circle%7D%3D2%5Ctimes%203.14%5Ctimes%2050%5Ctext%7B%20ft%7D)
![\text{Circumference of circle}=100\times 3.14\text{ ft}](https://tex.z-dn.net/?f=%5Ctext%7BCircumference%20of%20circle%7D%3D100%5Ctimes%203.14%5Ctext%7B%20ft%7D)
![\text{Circumference of circle}=314\text{ ft}](https://tex.z-dn.net/?f=%5Ctext%7BCircumference%20of%20circle%7D%3D314%5Ctext%7B%20ft%7D)
Therefore, the distance around the track is 314 feet and option C is the correct choice.
