Surface Area And Volume
The radius of a sphere is 4 cm . it is melted and drawn in to a wire of radius 0.03 cm .Find the length of the wire.
FORMULA OF VOLUME OF SPHERE IS
r = Radius
h = Height
Volume of sphere (V) = 4 / 3 * π * r3
Volume of cylinder (v) = π * r2 * h
Volume of sphere (V) = Volume of cylinder (v)
(4/3)πr3 = πr2h
(4/3) * 4 * 4 * 4 = 0.03 * 0.03 * h
85.333333333333 = 0.0009h
94814.814814815 cm = h
948.14814814815 m = h
Length of the wire is 948.14814814815 m.
