If the apothem is 13 square root 3 ft what is the area of the hexagon

dimulka [17.4K]

Answer:

The area of the hexagon is $1,014\sqrt{3}\ ft^{2}$

Step-by-step explanation:

we know that

The area of a regular hexagon is equal to

$A=\frac{1}{2}Pa$

where

P is the perimeter

a is the apothem

Find the length side of the hexagon

Let

b-----> the length side of the hexagon

Remember that

The formula to calculate the length side given the apothem is equal to

$b=\frac{2a}{\sqrt{3}}$

we have

$a=13\sqrt{3}\ ft$

substitute

$b=\frac{2(13\sqrt{3})}{\sqrt{3}}$

$b=26\ ft$

<em>Find the perimeter P</em>

$P=6b=6(26)=156\ ft$

<em>Find the area of the hexagon</em>

$A=\frac{1}{2}(156)(13\sqrt{3})=1,014\sqrt{3}\ ft^{2}$

A slice of pizza whose edges form a 42degrees angle with an outer crust edge 4 inches long was found in a gym locker. What was t

ira [324]

Answer:

10.9 inches.

Step-by-step explanation:

We have been given that a slice of pizza whose edges form a 42 degrees angle with an outer crust edge 4 inches long was found in a gym locker. We are asked to find the diameter of the original pizza.

We will use arc length formula to solve our given problem.

$s=r\theta$ , where,

s = Perimeter or circumference of circle,

r = Radius,

$\theta$ = Angle in radians.

Let us convert 42 degree to radians.

$42^{\circ}\times\frac{\pi}{180^{\circ}}=\frac{7\pi}{30}$

$4=\frac{7\pi}{30}\cdot r$

$r=\frac{120}{7\pi}$

$r=5.45674090$

We know that diameter is two times radius, so

$\text{Diameter}=5.45674090\times 2$

$\text{Diameter}=10.9134818\approx 10.9$

Therefore, the diameter of the original pizza was approximately 10.9 inches.
