Mathematics

a The center of the hexagon and of the circle are the same point. Also length of one side of the hexagon = 90/6 = 15 units.

If we join each vertex of the hexagon to the center then we get 6 equilateral triangles (because internal angle of reg hexagon = 120 and vertex angles of the triangles = 60) so the radius = length of side of hexagon = 15 units (answer)

b Area = pi * 15^2 = 706.9 units^2 to nearest tenth. Answer

help pls The circumference of the hub cap of a tire is 80.1 centimeters. Find the area of this hub cap. Use 3.14 for pi. Use pen
Liula [17]

Answer: The area is 510.25 cm². If the circumference of the cap were smaller then the area would be smaller as well

Step-by-step explanation:

First, you must find the radius

<em>80.1 ÷ 3.14 = 25.5</em>

<em>25.5 ÷ 2 = 12.75 <---- radius</em>

Then from that, you find the area

A=πr²

<em>12.75² = 162.5</em>

<em>162.5 × 3.24 = 510.25</em>

<em></em>

<em>Hope this was helpful!</em>

Grandpa schmidt is 75 years old. this is 9 years less than seven times the age of junior schmidt. how old is junior
Ad libitum [116K]
Grandpa's age is 75 years
Seven times the age of junior = age of grandpa + 9 jears = 75 + 9 = 84 years
Hence, the age of junior will be 84 / 7 = 12 years. (Since 84 is seven times his age, you have to devide by seven).
--> Junior is 12 years old.
