What is the approximate area of a circle enclosed by a piece of rope 50.24 inches long? (Use the fact that π ≈ 3.14 to make your

Nikitich [7]

Answer:

the approximate area of this circle is 200.96 inches long.

Step-by-step explanation:

To answer this problem we need to remember that the area of a circle is given by the formula:

Area = π $r^2$ where r is the radius.

and the perimeter is:

Perimeter = 2πr

Now, the problem tells us that the circle is enclosed by a piece of rope that's 50.24 inches long. So the perimeter of the circle is 50.24 inches.

Since we have the value of the perimeter and the value of pi, we are going to substitute these values in the perimeter formula to find r.

Perimeter = 2πr

50.24=2(3.14)r

50.24= 6.28r

50.24/6.28= r

8= r

Thus, the radius of the circle is 8 inches long.

Now, we can use this value to find the area of the circle:

Area = π $r^2$

Area = π $8^2$

Area = 3.14 (64)

Area = 200.96

Therefore, the approximate area of this circle is 200.96 inches long.

I need help it’s a quiz

solmaris [256]

Answer:

Question 6: 26 crowns plus 15 ribbons.

Question 7: 10 footballs plus 42 basketballs.

Step-by-step explanation:

Question 6 explanation: Since the expression is 22 crowns plus 13 ribbons plus 2 ribbons plus 4 crowns, you can think of the different items as variables in an equation. Picture crowns are the variable $x$ , and ribbons as the variable $y$ , this will help you solve the equation in an easier way that allows you to comprehend each step better. The equation will now be $22x+13y+2y+4x$ , in order to find how many $x$ (crowns) and $y$ (ribbons) you have, you need to combine like terms in the expression. In other words, add the terms with the variable $x$ together, and add the terms with the variable $y$ together. Simplified, the equation will be $26x+15y$ . Since the variables $x$ and $y$ were used to represent crowns and ribbons respectively, that means the correct answer is 26 crowns plus 15 ribbons.

Question 7 explanation: You can use the same method as you did in question 6, think of footballs and basketballs as the variables $x$ and $y$ respectively. The equation will be $16x+38y-6x+4y$ = $10x+42y$ . Since the variable $x$ was used to represent footballs and the variable $y$ was used to represent basketballs, that means the correct answer would be 10 footballs plus 42 basketballs.
