Volume of the sphere =( 4/3 π r3 ) cubic unit, If r = 2r then, Volume of the sphere: = = = 32/3 π r3.

use formula 4/3pie r cube
Comments

V=32/3*πr^3

Teacher

formula used is 4/3 pie r cube so volume of sphere is 67.04 r cube
Comments

If radius is 2r, volume is32/3 pi rcube
Comments

None because sum of angles of a triangle is 180 degrees
Comments

Volume of sphere -4/3pie r cube So V-32/3pie r cube
Comments

Given Radius = 2r Volume of sphere = (4*pi* radius^3)/3 = (4*pi*(2r)^3)/3 = (32*pi)/3 cubic units

32/3×π×r×r×r

radius of the sphere=2r The volume of a sphere = 4/3×?×r^3 =4/3×?×(2r)^3 =4/3×8r^3 =32/3×?r^3

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.
