Question

1.calculer air of a sphere of radius 7 cm, giving an exact value and an approximate value MM Caré 2.calculer the volume of the ball of radius 7 cm, giving an exact value and an approximate value MM cube

Answer 1

The volume of a sphere is (4/3) (pi) (radius)³ .

If the radius is 7cm, then the volume is

(4/3) (pi) (7³) =

(4/3) (pi) (343) =

(457 and 1/3) (pi) cm³ (exact)

1,436.76 cm³ (rounded)
