What is the total volume of pepsi in this pack of 12? Each cylindrical can has a radius of 1.25in and a height of 4.5in
Alecsey [184]
Total Volume of pepsi in this pack of 12 is 244.3308 in³.

Given:
12 Cylindrical can
radius of 1.25 in
height of 4.15 in

Find total volume:

Volume = π r² h  where π = 3.14
V = 3.14 * (1.25in)² * 4.15 in
V = 3.14 * 1.5625 in² * 4.15 in
V = 20.3609 in³

Volume of 20.3609 in³ is only good for one can. There are 12 cans. 

Total Volume = 20.3609 in³ x 12 cans = 244.3308 in³

Solve the equation by the Quadratic Formula. Round to the nearest tenth, if necessary. Write your solutions from least to greate
Marat540 [252]

I hope the choices for the numerators of the solutions are given.

I am showing the complete work to find the solutions of this equation , it will help you to find an answer of your question based on this solution.

The standard form of a quadratic equation is :

ax² + bx + c = 0

And the quadratic formula is:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

So, first step is to compare the given equation with the above equation to get the value of a, b and c.

So, a = 10, b = -19 and c = 6.

Next step is to plug in these values in the above formula. Therefore,

So,

So,

Hope this helps you!

Given is triangle with base = 10 cm and perpendicular height = 3 cm.

We know the formula for area of triangle is given by :-

Area = \frac{1}{2} × (Base) × (perpendicular height)

Area = \frac{1}{2} × (10) × (3)

Area = \frac{30}{2}

Area = 15 cm²

So, final answer is 15 cm².
