Circumference of circle: The distance around the circular region is called its circumference. The ratio of circumference of any circle to its diameter is constant. This constant is denoted by π and is read as pie.

Circumference/Diameter = Pie

i.e., c/d = π or c = πd

We know that diameter is twice the radius, i.e., d = 2r

C = π × 2r

⇒ C = 2πr

Therefore approximate value of π = 22/7 or 3.14.

By adding mid observations and divide it by 2

Arya Anupam 6 years, 1 month ago

First arrange the data. Then add the two numbers of middle and divide it by two. For example, Data= Number of shoes of different people:- 3,2,5,4,9,7. Solution= Arranged data= 2,3,4,5,7,9. We have to find its median (which means middle). Total no. of shoes of people is 6 which is an even number. Its middle numbers are 4 and 5. After adding 4 and 5 we got 9. Divide 9 (or sum) by 2. After dividing we got 4.5, So median of this data is 4.5. THANKS.

First term*fourth term= second term*third term. So, third term=first term*fourth term/second term. First term=6, Second term=18, third term=x Fourth term =24. So,x=6*24/18=8. Therefore, third term is 8. THANK YOU.
