  1. Answer:

    77 cm^3

    22 m^3

    22 kl^3

    Step-by-step explanation:

    volume of a cylinder = nr^2h

    n = 22/7

    r = radius

    the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

    A radius is half of the diameter

    1. Radius = 3.5 / 2 = 1.75

    Volume = (22/7) x (8) x 1.75^2 = 77 cm^3

    2. radius = 2/2 = 1m

    Volume = (22/7) x (7) x 1^2 = 22 cm^3

    1 meter = 1 kilolitre

    capacity = volume

    capacity = 22 kl^3
