1. Maths H oliday Homework Presentation on Tourism in Arunachal Pradesh

2. Concept used: Arithmetic Progression Avika and Dakshita visits a temple in A runachal Pradesh, avika jumps 1 stair of 10cm, dakshita jumps (2 stairs), avika then jumps 3 stairs. Find how much cms will dakshita jump next? A.P. = a+(n-1)d =10+(4-1)10 = 40cm Therefore, dakshita will jump 40cm

3. Concept used : Probability Avika and H emanshi visits a beach and goes for a swim. Suddenly a high tide came and one of them slipped and fell down. The probability that it was A vika is? Total outcomes= 2 girls P(E)= no. of favourable outcomes Total no. of outcomes = 1 2

4. Concept used: volume The picture depictsthe famous “Buddhist wheel” in arunachal Pradesh. One can calculate volume by the following steps: Volume of cylinder= π R 2h 3.14x13x13 =4116.54 c m 2

5. Concept used: height and distances This picture shows a famous Shiva Linga of Arunachal Praadesh . We need to find the distance between observer and top of shivling TanA = Perpendicular Base A= 30 1/ = 7.5/ base Base= 7.5 Therefore, the distance is 7.5 cm  

6. Concept used: height and distances Picture shows a Buddha Murti . The observer observes the temple with 60 degree. He observed bottom at 30 degree. Find the height of statue SinA = P/H ½=P/12 P=6cm Total height = 6+12= 18 cmz

7. Concept used: Probability More than half of the fields in AP are Bamboo’s. Lets calculate the volume of it. Volume of Bamboo= π R 2h =3,14 x 2 x 2 x 10 =125.6 cm3 So, volume of all 3 rrings of bamboo = 125.6 x 3 =376.8 cm3
