express 81 = 3x as a logarithmic equation.

a. log381 = x
b. log3x = 81
c. log813 = x
d. log81x = 3

Option A

Step-by-step explanation:

Use logarithmic rules:

Given the equation:

Taking both side logarithm function:

Divide both sides by log 3 we have;

Apply the logarithmic rules:

therefore, as a logarithmic equation is

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.
