Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(5, 1), B(7,1) C(7, 6) and
D(5, 6) What is the perimeter of rectangle ABCD units
1 answer:
Answer: perimeter is 14 units
Explanation:
You could use the distance formula to find the lengths of segments AB, BC, CD, and DA; or you could graph rectangle ABCD and note that you can count out the spaces to find the lengths of each side. Option 2 is easier in my opinion. Check out the diagram below. The horizontal portion is 2 units and the vertical part is 5
perimeter = 2*(length+width)
perimeter = 2*(5+2)
perimeter = 2*7
perimeter = 14

Answer:
The candle will not use all the paraffin from the original block.
Step-by-step explanation:
The cone-shaped candle is 5 cm wide at the base i.e. the diameter of the base is 5 cm i.e. radius is 2.5 cm.
If the height of the cone is 25 cm, then total volume of the cone shaped candle is
=
= 163.69 cubic cm.
Again, the volumes of the rectangular block of paraffin is (4 × 8 × 6) = 192 cubic cm.
Since, 192 > 163.69
Therefore, the candle will not use all the paraffin from the original block.
