Find the area of a regular hexagon with side length 10 m. Round to the nearest tenth.​
Maksim231197 [3]

Answer:

A=259.8\ m^2

Step-by-step explanation:

we know that

The area of a regular hexagon is the same that the area of 6 equilateral triangles

The area of 6 equilateral triangles applying the law of sines is equal to

A=6[\frac{1}{2}b^2sin(60^o)]

where

b is the length side of the regular hexagon

we have

b=10\ m

substitute

A=6[\frac{1}{2}(10)^2sin(60^o)]

A=259.8\ m^2

Murrr4er [49]
The probability is 0.9671.

The z-score for this is given by

z = (x - μ)/(σ/√n)
z = (38000-37500)/(1561/(√33)) = 1.84.

Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of, less than, this is 0.9671.
