pls check weather my answers are correct..

[sunny.raavi1990]

dude can u xplain 1,3,5??

[nehareddy4u]

6. i think its 4%

[nehareddy4u]

1. diameter = 12.. radius =6..
given isosceles triangle.. and height = 6 (as radius)..
so it is a 90 45 45.. (SRT) so sides will be 1:1: 2^0.5..

find the area of the triangle, arc separately.. u will get..

[sunny.raavi1990]

even 6th i got approx 4 ....

[sunny.raavi1990]

@neha its nt mentioned that its right angled isc so how can u consider it as s:s:s^0.5 ?? and how did u take diameter as height

[xyz123]

6th is apprx 4
xplain 7th... im gtng 1/2

[nehareddy4u]

sunny.ravi

when ever the a triangle is formed by toching the ends of diameter and the circle.. the angle is 90'..

Explanation for 3rd please

[varun kumar]

hi friends..... can u explain the 6th question. i think it is 5/16

[pravita]

can some explain 3 and 5 pls??

[pravita]

which way shud we take 8th .....a1=25 a2=23 or vice versa.....kindly explain
