Answer:
So the discount is 33% and we are paying 67% of the value. The reason is given by the relative change:
Step-by-step explanation:
First we have a first discount of 40% so then using this condition and assuming that represent the initial price, the price after the first discount
is given by:
That means 60% of the original value.
Now we have another discount of 45% for the 60% reamining after a 2 discount so let's represent the price after the second disccount we can can express this price in terms of
or
liek this:
So the discount is 33% and we are paying 67% of the value. The reason is given by the relative change:
Answer:
area of circle in terms of π is
Step-by-step explanation:
The endpoints of a diameter of a circle are A(3,2) and B(6,6). Find the area of the circle in terms of π.
The formula used to find area of circle is:
We need to find radius of circle. For finding radius we will first find diameter of circle using distance formula.
Finding distance between points A(3,2) and B(6,6) using distance formula.
We have
Putting values and finding distance
So, distance is 5, we can say that diameter of circle = 5
The formula used to find area of circle is:
We need radius, so we know that r = d/2 so, radius = 5/2 = 2.5
Now finding area in terms of π
So, area of circle in terms of π is
