Which of the numbers below correctly describes 4.7 h?

Vera_Pavlovna [14]

Answer: a. 4,700 mh

Step-by-step explanation:

Assuming:

$1 mh = 10^{-3} h$

$1 kh = 10^{3} h$

$1 ph = 10^{-12} h$

The only option that is correct is a. 4,700 mh, let's prove it with the following conversion:

$4.7 h \frac{1 mh}{10^{-3} h} = 4,700 mh$

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.
