Evaluate log3^8, given log3^2 is equivalent to 0.631
elixir [45]

We will use the followin property of logarithms:


log(a^b) = b log(a)


So, we have


log(3^2) = 2 log(3) = 0.631


If you multiply both sides by 4, you get


8log(3) = log(3^8) = 2.524

A cylinder has a base diameter of 16 feet and a height of 19 feet. What is its volume in cubic feet, to the nearest tenths place
Tresset [83]

Answer: Volume = 3818.2 cubic feet

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

Diameter = 16 feet

Radius = diameter/2 = 16/2

Radius = 8 feet

Height = 19 feet

Therefore,

Volume = 3.14 × 8² × 19

Volume = 3.14 × 64 × 19

Volume = 3818.2 cubic feet rounded to the nearest tenth
