AnswerAnswerAnswerAnswer: C = πd = 65π = 204.2 cm
Step-by-step explanation: C = pi*d
where d is the diameter.
First we get the circumference, then we multiply it by the number of revolutions, which is 20:
C = 3.14 * 65
C = 204.1 cm (this is only equal to 1 revolution)
Therefore, total distance travelled in after 20 revolutions is
204.1 * 20 = 4082 cm
Answer:
[see below]
Step-by-step explanation:
- All natural numbers, whole numbers, integers, fractions (with integers), and numbers with terminating or repeating decimals are rational.
- Irrational numbers cannot be written as fractions with integers. This includes non-germinating and non-repeating decimals.

Answer:
Maximum safe height can be reached by ladder = 15.03. ft
Step-by-step explanation:
Given,
Let's assume the maximum safe height of wall = h
angle formed between ladder and ground = 70°
length of ladder = 16 ft
From the given data, it can be seen that ladder will form a right angle triangle structure with the wall
So,from the concept of trigonometry,
![Sin70^o\ =\ \dfrac{\textrm{maximum safe height of wall}}{\textrm{length of ladder}}](https://tex.z-dn.net/?f=Sin70%5Eo%5C%20%3D%5C%20%5Cdfrac%7B%5Ctextrm%7Bmaximum%20safe%20height%20of%20wall%7D%7D%7B%5Ctextrm%7Blength%20of%20ladder%7D%7D)
![=>Sin70^o\ =\ \dfrac{h}{16\ ft}](https://tex.z-dn.net/?f=%3D%3ESin70%5Eo%5C%20%3D%5C%20%5Cdfrac%7Bh%7D%7B16%5C%20ft%7D)
![=>\ h\ =\ 16\times Sin70^o](https://tex.z-dn.net/?f=%3D%3E%5C%20h%5C%20%3D%5C%2016%5Ctimes%20Sin70%5Eo)
=> h = 16 x 0.9396
=> h = 15.03 ft
So, the maximum safe height that can be reached by the ladder will be 15.03 ft.
