Answer:
Step-by-step explanation:
This is one of those formulas of algebra and geometry that you need to learn. If you know the radius and the height of a vertical cylinder, then its volume is equal to the (base area) times the (height), which, symbolically, are
V = (base area)(height)
Here,
V = πr²· h where πr² is the area of the base (which is a circle of radius r) and h is the height of the cylinder.

Step-by-step explanation:
Step-by-step explanation:
Step 1: Set up the formula for the surface area of a regular pyramid.
SA =
where :
- SA equals the total surface area of the pyramid,
- p equals the perimeter of the base,
- h equals the slant height of the pyramid
- B equals the area of the base.
Step 2: Plug the perimeter of the base into the formula
you can calculate the perimeter by multiplying the length of one edge by the number of edges.
Step 3: plug the value of the slant height into the formula (it is not the perpendicular height)
Step 4: find the area of the base (depend on the shape of the base)
Hope it will find you well.
Answer:
B) 6 tan(35°)
Step-by-step explanation:
from the right angle tan° = opposite / adjacent
therefore tan (35°) = (x) / 6
by multiplying 6 to both sides
tan (35°) * 6 = (x) / 6 * 6
therefore (x) = 6 tan (35°)
