Easy Question, Easy PointsTopic: Volume

Answer 1

Answer:

1) 125,600 cm³

2) 327,910.2 m³

Step-by-step explanation:

Volume of cylinder: pi × r² × h

1) 3.14 × 20² × 100

125,600 cm³

2) 3.14 × (118/2)² × 30

327,910.2 m²

Answer 2

Answer:

a   125600 cm^3

b    327910.2 m^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

a   = 3.14 (20)^2 100

  =125600 cm^3

b  We know the diameter  r =d/2 = 118/2 =59

V = pi r^2 h

         3.14 (59)^2 *30

        327910.2 m^3
