The circumference of a circular design is 2020 inches.

What is the length of its diameter?

Use 3 . 143.14 as an approximation for \mathrm{\pi }π.

Diameter of the circle is twice it's radius D=2r.

Circumference of the circle is 2πr.

According to the above problem,

2π(radius)=20 inches

2(radius)=20/π=20/3.14

Diameter=6.37 inches

step-by-step explanation:

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
