Students were asked over to answer a question at education and to declare what is most important for them to succeed. Of the many replies, one that that stood out was practice. Successful persons are generally not born successful; they become successful thru hard work and commitment. If you want to attain your goals, keep this in mind! shown below are one of the answer and question example that you would probably use to practice and supercharge your information and also give you insights that would guide you to sustain your study in school.

## Question:

A company that manufactures storage bins for grains made a drawing of a silo. The silo has a conical base, as shown below:Which of the following could be used to calculate the total volume of grains that can be stored in the silo?

A. π(8.5ft)2(2ft) + one over three π(2ft)2(13ft − 8.5ft)

B. π(2ft)2(8.5ft) + one over three π(2ft)2(13ft − 8.5ft)

C. π(8.5ft)2(2ft) + one over three π(13ft − 8.5ft)2(2ft)

D. π(2ft)2(8.5ft) + one over threeπ(13ft − 8.5ft)2(2ft)

## Answer:

**Option B is correct. **

The **storage bin** is **constructed** using **a cylinder** and **a cone**. Hence the total volume of the grain can be calculated using the formula;

Vc is the volume of the cylinder

Vco is the volume of the cone.

__For the cylinder:__

Height of the cylinder hc = 8.5ft

radius rc = 4/2 = 2ft

__For the cone:__

Height of the cone = (13 – 8.5)ft

radius of the cone = radius of the cylinder rco = 2ft

Taking the sum of the volumes;

This shows that **option B** is correct.

They can potentially hopefully help the student handle the question by implementing the questions and answer examples. You possibly will then have a discussion with your classmate and continue the school learning by studying the question as a group.
