Chapter 12, Problem 20MCQ

To determine

To find the volume available for carrying instruments and cameras in cylinder shaped body of TIROS satellite.

Answer to Problem 20MCQ

  $26,310$ cubic inches

Explanation of Solution

Given:

Cylindrical body of TIROS satellite:

Diameter of the cylindrical body $=42$ inches

Height of the cylindrical body $=19$ inches

Formula used:

Volume of the cylinder $=\pi r^{2}h$

where $r$ is the radius and $h$ is the height of the cylinder.

Calculation:

Given, diameter of the cylindrical body $=42$ inches

So, radius of the cylindrical body $=\frac{diameter}{2}$

  $\Rightarrow \frac{42}{2}$

  $\Rightarrow r=21$ inches

To find volume of the cylinder, use the following formula.

Volume $=\pi r^{2}h$

Now, putting the values of $r$ and $h$ ,

  $\Rightarrow 3.14\times 21\times 21\times 19$

  $\Rightarrow 26,310$ cubic inches

Conclusion:

Hence, the volume available for carrying instruments and cameras is $26,310$ cubic inches.
