sphere

    Cards (5)

    • the vol of a sphere is 4/3 pi times the cube of the radius.
      use pi = 3.14 and r - radius
    • vol - 4/3 x pi x r3 or 4 pi r3 divided by 3
    • solve, given , r - 7m
      =4 x 3.14 x 7 x 7 x 7 divided by 3
      multiply the radius, then by 4 then by pi and then divide by 3
      = 4,308. 08 m3 divided by 3
      vol - 1, 436.03 m 3
    • Radius: a straight line from the centre to the circumference of a circle or sphere.
    • diameter: a straight line passing from side to side through the centre of a body or figure, especially a circle or sphere.
