Question

PLS HELP ( CORRECT GETS BRAINLY )

A cork in the shape of a cylinder has a radius of 2 cm, a height of 5 cm, and weighs 2.5 grams.

Answer 1

a). Volume = 62.86 cm³

b). Density of the cork = 0.03977 gms per cm³

Step-by-step explanation:

A cork in the shape of a cylinder has the radius 'r' = 2 cm

and height of the cork = 5 cm

a). Formula for the volume of the cork = pie×r²×h

Where r = radius of the cork

h = height of the cork

V = pie × 2² ×5

  = 20π

  = 62.86 cm³

Therefore, volume of the cork is 62.86 cm³.

b). Formula for cork's density = mass/volume

                                                 =2.5/62.86

Therefor, Density of the cork = 0.03977 grams per cm³
