What is mean by Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Radius of hemisphere = 39.4 feet

Now, We know that;

The volume of a hemisphere = (2/3)πr³ cubic units.

Hence, We get;

The volume of a hemisphere = (2/3)π (39.4)³ cubic units.

= 2/3 × 3 × 61,162.98

= 122,325.97 cubic units

Thus, The volume of a hemisphere with a radius of 39.4ft, rounded to the nearest tenth of a cubic foot is,

⇒ 122,325.97 cubic units
