To solve this, we are going to use the formula for the area of a regular polygon knowing its apothem:
where
is the area of the regular polygon.
is the apothem (the perpendicular distance from the center to a side)
is the number of sides of the regular polygon.
is the trigonometric function tangent
We can infer from our picture that our regular polygon has 6 sides, so
. We also know that the apothem (the perpendicular distance from the center to a side) of our regular polygon is 18m, so
. Lets replace those values in our formula to find
:
We can conclude that the area of our regular polygon is
1122.4 square meters.
Answer:
55.5 kg.
Step-by-step explanation:
Potential energy = mgh
= m * 9.81 * 4.5 = 2450 where m is the mass of the man.
m = 2450 / (9.81* 4.5)
= 55.5 kg.
It important because when you round the decimal it helps you get closer to the whole then you can divide the whole and the other whole then you get your answer
if she doesn't spend a penny, could it be(1.08)^12×$8.333?
