to the nearest square unit what is the area of a regular octagon with a side length of 15 and an apothem of 18.1
guajiro [1.7K]
To find the area of a regular octagon, you can split the shape into eight congruent triangles from the center, find the area of one triangle, and then multiply it by eight.

If you use this method, you will find that the base of the triangle is the side length of the octagon (in this case, 15 units), and that the height is the apothem (in this case, 18.1 units).

From here, you can use the basic formula used to find the area of a triangle:
A = 1/2bh
A = 1/2 (15) (18.1)
A = 135.75 square units

Finally multiply the area of that triangle by eight.
8(135.75) = 1086 

The area of the octagon is 1086 square units.

Aliun [14]

If you would like to know the equation for the above expression, you can calculate this using the following steps:


x ... the number

x * 1/3 inches = 5/6 inches

x * 1/3 = 5/6     /*3/1

x = 5/6 * 3

x = 5/2 = 2 1/2

Bill's golf bag contains 9 white golf balls, 6 yellow golf balls, 1 orange golf ball, and 1 pink golf ball. Without looking, Tim
BaLLatris [955]

Answer:

The correct answer is 0.0330 and the events are independent.

Step-by-step explanation:

Total number of balls in Bill's golf bag = 17

Let A be the event of drawing a white ball and B be the event of drawing an orange ball.

Number of white balls Bill has in his bag is 9.

Probability of the event A in the first draw = \frac{9}{17}

Number of orange ball in Bill's bag is 1.

Probability of event B in the second draw = \frac{1}{16}

Thus total probability for Tim to tee off with a white ball and putt with an orange ball = \frac{9}{272} = 0.0330

The above events are independent on each other.
