Question

An office uses paper drinking cups in the shape of a vine either dimensions as shown to the nearest tenth of a cubic inch what is the volume of each drinking cup

Answer 1

Answer:

$V=7.91\ \text{inches}^3$

Step-by-step explanation:

An office uses paper drinking cups in the shape as attached.

The diameter of the cup = 2 3/4 inches

= 11/4 inches

The height of the cup, h = 4 inches

The radius of the cup, r = 1.375 inches   (As r = d/2)

We need to find the volume of the drinking cup. It is in the shape of a cone. The volume of a cone is given by :

$V=\dfrac{1}{3}\pi r^2 h$

Substituting the values of r and h

$V=\dfrac{1}{3}\pi \times (1.375)^2 \times 4\\\\=7.91\ \text{inches}^3$

Hence, the volume of each drinking cups is $7.91\ \text{inches}^3$.
