Question

A water bottle is in the shape of a cylinder. It is 18 centimeters high and has a diameter of 7 centimeters. What is the total mass of water it can hold if 1 cubic centimeter of water is equal to 1 gram? Round to the nearest tenth.

Answer 1

692.4 g

Explanation:

Given :

Height, h = 18

Diameter = 7 ; Radius, r = 7/2 = 3.5

I cm³ = 1 g

Volume of a cylinder, V

V = pi * r² * h

V = 3.14 * 3.5^2 * 18

V = 3.14 * 12.25 * 18

V = 692.37 cm³

Since,

1cm³ = 1g

Hence, the total mass it can hold is :

692.4 g of water.
