Find the radius of the cylinder with height 6 cm with volume 54 cubic cm
Lubov Fominskaja [6]
V = pi r^2 h
54 = 3.14 * r^2 * 6
54 = 18.84 r^2
Divide both sides by 18.84
r^2 = 2.866
Square root both sides
r = 1.7

Calculate the quotient below and give your answer in scientific notation.<br> 2.64*10^-3\8.0*10^0
Zolol [24]

Answer:

The quotient of: \frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0} is: \mathbf{3.3\times 10^{-4}}

Step-by-step explanation:

We need to find quotient of: \frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}

We know that 10^0=1

Now solving:

\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}\\=\frac{2.64\cdot 10^{-3}}{8.0}\\=\frac{0.00264}{8}\\=0.00033

Writing it in scientific notation

0.00033\\=3.3\times10^{-4}

So, the quotient of: \frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0} is: \mathbf{3.3\times 10^{-4}}
