To answer the question being asked, we need the expression for the area of a regular pentagon. It is expressed as:

A=(1/4) (a²) (√5(5+(2√5))


A=(1/4) (6²) (√5(5+(2√5))
A = 61.94

Therefore, the correct answer from the list of choices is the third option.

the relationship between the relative size of an earthquake, S, and the measure of the earthquake on the Richter scale, R, is gi

omeli [17]

Answer:

Relative Size, S, is 1584.89

Step-by-step explanation:

The equation is $R=log_{10}(S)$

Where,

R is the measurement in Richter Scale
S is the relative size of the earthquare

It is given that in Richter Scale, an earthquake measured 3.2, so $R=3.2$ .

They want to know relative size, S, so we put given information in equation and solve for S:

$R=log_{10}(S)\\3.2=log_{10}(S)$

Converting to exponential form, we have:

$3.2=log_{10}(S)\\S=10^{3.2}\\S=1584.8932$

Rounding to nearest hundredth, we have:

$S=1584.89$
