I keep putting in the formula but I keep getting the answer wrong

Advocard [28]

Answer:

314 in² (nearest whole number)

Step-by-step explanation:

Radius of a regular polygon: The distance from the center of the polygon to any vertex. The radius of a hexagon is equal to the length of one side.

Therefore, from inspection of the given diagram:

radius = 11 in ⇒ side length = 11 in

To find the area of a regular polygon, we first need to calculate the apothem. The apothem is the line drawn from the center of the polygon to the midpoint of one of its sides.

$\textsf{Length of apothem (a)}=\dfrac{s}{2 \tan\left(\frac{180^{\circ}}{n}\right)}$

where:

s = length of one side
n = number of sides

Given:

s = 11 in
n = 6

Substitute the given values into the formula and solve for a:

$\implies \textsf{a}=\dfrac{11}{2 \tan\left(\frac{180^{\circ}}{6}\right)}=\dfrac{11\sqrt{3}}{2}$

Area of a Regular Polygon

$\textsf{A}=\dfrac{n\:s\:a}{2}$

where:

n = number of sides
s = length of one side
a = apothem

Given:

n = 6
s = 11

$\textsf{a}=\dfrac{11\sqrt{3}}{2}$

Substitute the given values into the formula and solve for A:

$\implies \sf A=\dfrac{6 \cdot 11 \cdot \dfrac{11\sqrt{3}}{2}}{2}$

$\implies \sf A=314.3672216...$

$\implies \sf A=314\:\:in^2\:\:(nearest\:whole\:number)$

Work out 2/15 of 5 Give your answer as a fraction in its simplest form.

docker41 [41]

Answer:

2/3

Step-by-step explanation:

2/15 of 5

Of means multiply

2/15 * 5

Multiply the numerators

2*5 = 10

Put over the denominator

10/15

We can divide the top and bottom by 5

10/5 =2

15/5 =3

Graph the linear equation. Find three points that solve the equation then plot them on the graph 3x-4y=-18

Mazyrski [523]

Answer:

point (0, 4.5)

point (-6, 0)

point (1 , 5.25)

Step-by-step explanation:

The first step is to introduce values of x to the function to obtain three points that belong to the equation $3x-4y = -18$

x = 0

$3(0) -4y = -18\\\\y = 18/4 = 4.5$

point (0, 4.5)

y = 0

$3x-4(0) = -18\\\\x = -6$

point (-6, 0)

x = 1

$3(1) -4y = -18\\\\-4y = -18-3\\\\y = 21/4 = 5.25$

point (1 , 5.25)

The graph of the function is shown in the attached image
