much rope with the gym teacher need .
<u>Step-by-step explanation:</u>
Here we have , In the gym there is a round metal pole that is 8 inches in diameter. The gym teacher wants to wrap the pole tightly with 1-inch thick rope from the ground up to a height of 6 feet. (The rope will be wound over and over until it reaches a height of 6 feet.) We need to find About how much rope with the gym teacher need . Let's find out:
According to question , the rope is covered in lateral surface area of a cylinder i.e. to wrap the pole tightly with 1-inch thick rope from the ground up to a height of 6 feet which will cover lateral surface area of cylinder . We know that Formula for lateral surface area is :
⇒
From the question we have
Now , height of pole is 72 inches and we will wrap pole with 1 inch thick rope , So total number of turns of rope in pole :
⇒
⇒
Now , Length of one turn of rope in pole is equivalent to circumference of circle with radius = 4 inches as:
⇒
⇒
⇒
Since , length of one turn is 25.12 inch so ,length of total rope i.e. of 72 turns is :
⇒
⇒
Therefore , much rope with the gym teacher need .
According to the amount he drove in 5 hours, he drove an average of 62 MPH. If he continued to drive at this speed for 8 hours, he would travel 496 miles.
If we are solving for x then it would be -1 :)
I think it's because of the issue of sustainability and pollution. Many companies have been expanding their business in Florida. Florida used to be one of the best producers in the US. However, because of the on-going expansion, people moving in and out of the state can lead to overpopulation and shortage on food supply. Florida is also known for its marine ecology. Expansion can also <span>severe pollution and extinction of some animals that are found in the state</span>
