Answer:

452.16km^3

Step-by-step explanation:

The problem states a diameter, but we need a radius for the problem. So our radius is 12 (24/2).

Now we go by this formula= V=(3.14)r^2(h/3)

Since the radius is 12, we must raise it to the second power, which is 144. Then divide the height by 3, which is 1 (3/3). The 1 shouldn't matter because it's 1, so now we have to multiply 144 by 3.14. That is 452.16.

\frac{24}{2}=\\12\\\\V=\frac{1}{3}\pi r^2h=\\V=\frac{1}{3}(3.14)(12)^2(3)=\\V=452.16

Find the volume of the cylinder.<br> Either enter an exact answer in terms of π or use 3.14 for π
Alex787 [66]

Answer:

Volume of the cylinder = 62.80 units^3

Step-by-step explanation:

Height of the Cylinder(h)=5 units

Radius(r)=2 units

Volume of a cylinder=\pi *r*r*h

     Putting the values in the formula;

Volume of the cylinder =\pi *2*2*5

                      As,   \pi =\frac{22}{7}=3.14                        

Volume of the cylinder=  3.14*2*2*5

                                 =3.14*2*2*5\\\\=3.14*4*5\\\\=3.14*20\\\\=62.80units^3                              

The Volume of the cylinder is 62.80 units^3

Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. Se
Slav-nsk [51]

Answer:

-0.6309

Step-by-step explanation:

Using the change of base formula,

Log 1/2 to base 3 = Log1/2 ÷ Log 3 = Log 0.5 ÷ Log 3

Log 0.5 = -0.3010

Log3 = 0.4771

Log 0.5 ÷ Log 3 = -0.3010 ÷ 0.4771 = -0.6309
