PLEASE SHOW ALL WORK>

$2,895.19

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

P = initial balance

r = interest rate

n = number of times compounded annually

t = time

First, change 8% into its decimal form:

8% -> -> 0.08

Now lets plug in the values into the equation:

The final amount for this investment is $2,895.19

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
