Consider a regular pyramid A with a square base and a right circular cone B.

Angelina_Jolie [31]

Answer:

Pyramid

Step-by-step explanation:

$\text{Volume of a Square Pyramid }=\frac{1}{3} \times l^2 \times Height\\\\ \text{Volume of a Cone }=\frac{1}{3} \pi r^2 \times Height$

Given that the two solids have the same volume

$\frac{1}{3} \times l^2 \times Height=\frac{1}{3} \pi r^2 \times Height$

If the length of a side of the square base of pyramid A is the same as the base radius of cone B. i.e l=r

$\frac{1}{3} \times l^2 \times $Height of Pyramid=$\frac{1}{3} \pi l^2 \times $Height of cone$\\\\$Cancel out $ \frac{1}{3} \times l^2$ on both sides\\\\Height of Pyramid= \pi \times $ Height of cone$$

If the height of the cone is 1

$H$eight of Pyramid= \pi \times 1 \approx 3.14$ units$

Therefore, the pyramid has a greater height.

Give the coordinates of each point as an ordered pair

sergeinik [125]

Here are the coordinates for each.

H - (4,1)

I - (0,1)

J - (1,-3)

K - (-3,-4)

L - (-4,0)

M - (3,-2)

To find these simple go from the x axis (horizontal) to the y axis (vertical), labeling as "X,Y".
