Surface Area And Volume

Find the 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.
