How is a clock like a rotation

Mathematics

Reika [66]3 years ago

Rotation is defined as a circular movement of an object around a point or center of rotation. 

Based on the given definition, a clock is definitely like a rotation. Its clock hands form a circular movement on the face of the clock around the center of the clock. That is why rotation is identified as clockwise or counterclockwise. When you say clockwise, the movement of the rotation is the same as the movement of the clock hands. When you say counterclockwise, the movement of the rotation is the opposite direction of the movement of the clock hands.

Cone is formed from 3200 ft of gravel, if the height of the cone is 24 ft what is the radius in feet of the base of the cone
Lesechka [4]

Question :

Cone is formed from 3200 ft³ of gravel, if the height of the cone is 24 ft what is the radius in feet of the base of the cone

Answer:

11.3 feet

Step-by-step explanation:

The volume of a cone = πr²h/3

We are asked to find the radius

The formula is given as:

r = √3V/πh

V = 3200 ft³

h = 24 ft

r = √3 × 2400/π × 24

r = 11.28379 ft

Approximately = 11.3 ft

The radius in feet = 11.3 ft

Hello! I'm stuck on Pythagorean theorem in geometry. There are some numbers that suppose to have a line on top but I don't know
Darina [25.2K]

<u>Choice A: </u>2,2, \sqrt{4}<u />

<u>Choice B: </u>9, 40, 41

<u>Choice C: </u>\sqrt{5}, 10$ and  \sqrt{125}

Answer:

(B)9, 40, 41

Step-by-step explanation:

To check if the sides form a right triangle, you check to see if they satisfy the Pythagorean theorem.

Hypotenuse^2=Opposite^2+Adjacent^2

Note that the longest side length is always the hypotenuse.

<u>Choice A: </u>2,2, \sqrt{4}<u />

Now, \sqrt{4}=2

Therefore:

2^2\neq 2^2+2^2\\4 \neq 8

These side lengths form an equilateral triangle. They do not satisfy the theorem.

<u>Choice B: </u>9, 40, 41

The longest side length is 41.

41^2=1681

40^2+9^2=1681

Therefore:

41^2=40^2+9^2

These side lengths form a right triangle.

<u>Choice C: </u>\sqrt{5}, 10$ and  \sqrt{125}

\sqrt{5} \approx 2.24 \\ \sqrt{125}\approx11.18

Therefore, the longest side length is \sqrt{125}

(\sqrt{125})^2=125\\(\sqrt{5})^2+10^2=5+100=105\\\\(\sqrt{125})^2 \neq (\sqrt{5})^2+10^2

These side lengths do not form a right triangle.
