the length of the swimming pool is 8 m longer than its width and the area is 105 m squared write in quadratic equation
1 answer:
Answer:
Step-by-step explanation:
The length of the swimming pool is 8m longer than it's width.
If we say L = length, W = width
From the information above, we can say
L= 8 + w
We are also told the area is 105 m squared.
<em>Note: </em>
<em>Area of a Rectangle = Length x Width </em>
105 = (8 + w ) x w
Subtract 105 from both sides:

Answer: OPTION 1
Step-by-step explanation:
For this exercise you need to remember that, by definition, the Arc length can be calculated with the following formula:
where "C" is the central angle of the arc in radians and "r" is the radius.
Since you need to find the Central angle, you have to solve for "C" from that formula, as following:
According to the information given in the exercise, you can identify that:
Therefore, the final step is to substitute these values into the formula and evaluate, in order to find the value of "C":
