Hi

what traction of a day is 8 hours 

in the figure AB and CD are two diameters of a circle (with centre O) perpendicular to each other and OD is the diameter of the smaller circle. If OA  is equal to 7cm, find the area of the shaded region

3x +6y - 4z , -4y +3z -5x and -16z  - 7y + 8x

A water tank has steps inside it. Monkey ki is sitting on the the topmost step that is the first step. The water level is at the ninth step. 
I he jumps 3 steps down and then jumps back to step a full stop in how many jumps will he reached the water level question mark after drinking water he wants to go back for this he jumps 4 steps up and then jumps back 2 steps down in every move. In how many jobs will he reached back in the top step? III if the number of steps move down is represented by negative integer and the number of steps moved up by positive integer integers his moves in path I and II by completing the following a - 3 + 2 - dotdotdot is equal to minus 8 b 4 - 2 + dotdotdot is equal to 8 in a the sum - 8 represent going down by 8 steps so what will the Summit and be represent?

This question in some other method I need
