Answer:
The total surface area of a regular hexagonal pyramid is 146.2 cm².
Step-by-step explanation:
The base is a regular hexagon 4cm on a side. its height is 8 cm.
The total surface area of a pyramid with regular hexagon base

Where, a represents the base edge and h represents the height of the pyramid.
The area of given regular hexagonal pyramid is





The total surface area of a regular hexagonal pyramid is 146.2 cm².
We know there are 4 suites the deck can be divided into, and two of the 4 are black. So you divide 2/4, and get 1/2. So the probability that a black card will be chosen is 1/2.
each part of the box and whisker is 25% (meaning each quartile) There are 4 quartiles so this makes 100%
So, the first being 25% and this is where the below 15 falls.
So, 25%
