Answer:
B. 31.62
Step-by-step explanation:
First, find the distance of the line using the distance formula, . Plug the two points (-1,0) and (5,2) into the formula and solve. This gives you 6.32, then this is only one line of a pentagon, which has 5 sides, so you need to multiply. Since you are finding the perimeter, which is all of the sides added together, multiply the one side by 5. 6.32*5=31.62.
Answer:
Both volumes are the same
Step-by-step explanation:
Volume of cylinder =
r = radius
h = height
Since area of the circle is given on top,
Area of a circle =
We know the area is 12
12 = (we need to find r)
r =
r = 1.954
Now we can find the cylinder's volume:
Volume of cylinder = (6)
Volume of cylinder = 72
To find the volume of the cuboid, we use
Volume of cuboid = lwh
l = length
w = width
h = height
Volume of cuboid = 6 x 4 x 3
Volume of cuboid = 72
This proves that both the volumes are the same.
