Just to make it easy for you, I am making this statements. Simply remember the area of the circle = pi*r^2. Multiply this by another radius quantity so it becomes = pi*r^3. Now just multiply with 4/3 to get the volume of the sphere= 4/2*pi*r^3. To get hemisphere volume just divide by two (Hemisphere...

The angles of a triangle are arranged in ascending order of magnitude. If the difference between two consecutive angles is 10°, find all the three angles.
Let the any one of the angle of triangle be x then other two angle are x+10, x+20 According to Question, x + (x+10) + (x+20)=180 3x + 30 = 180 3x = 150 x = 50 Thus, angles would be 50, 60, and 70.

Given that HCF (161,345) = 23, find their LCM.
N¹ *N² = LCM * HCF 161 *345 =23 * N² N² =2415

Solve : 55x + 52y = 217; 52x + 55y = 217
subtract two equations from each other, we get x=y and then substitute x=y in any of the equation we get values for x and y . x=1.972 ,y= 1.972
