I need help solving equations of circles (8th grade Math homework).

the closer the value is to 1, the more circular the lake is. Formula = L — 2√(pi)π*A -The length of crater lake's shorline is about 26mi and is area is about 21. solve -suppose a lake is perfectly circular and has a 2 mi diameter. solve -evaluate the expression for 2 other perfectly circular lakes. you choose diameters. what do you see? -evaluate the expression for the lake of the ozarks. the length of shorline is 1350 and area is 93. solve

When dealing with a perfect circle (in your case, a hypothetical lake), then the following applies:

Circle Circumference = C

Circle Diameter = d

Circle Radius = d/2 or r

Circle Area = A

and,

Circumference (C) = pi * (d)

A = pi * (r)^2

Therefore, attempting to interpret the formula in your question, the following is offered:

For a...
