Solution:
Amount of juice hold by Cup B which is in the shape of a cylinder having width 2 inches that is radius 1 inches and height 7 inches
= [tex]\pi r^2 h= \pi \times 1^2 \times 7= 7 \pi[/tex] cubic inches
Amount of juice hold by cup A which is in the shape of a cone having width 2 inches that is radius 1 inches and height 3 inches
= [tex]\frac{1}{3} \times \pi \times r^2 h\\\\ = \frac{1}{3}\times \pi \times 1^2 \times 3=\pi[/tex] cubic inches
Amount of juice that cup B will hold than cup A when both are completely full = [tex]7\pi -\pi = 6 \pi[/tex] cubic inches
= 6 × 3.14
= 18.84 cubic inches
Option A: 18.8 cubic inches
