Answer:
Step-by-step explanation:
As you can see in the venn diagram that is attached below, The individuals that drink milk are in green, those that drink curd are in yellow, and those that drink both are in light blue. Since the sum of those that drink milk with those that drink curd is 110 and a total of 120 students were surveryed. Then this means that 10 of the students neither drink milk nor curd. These students are represented outside of the venn diagram but within the box of surveyed students.
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
