Lesson $3B-$ Lab $3-$ Circle Stuff Data File Input

Java Module $-$ Lesson $3$B $-$ Lab $3-$ Circle Stuff

Write a program to input from a data file the radius values of two circles into double variables radl and rad$2.$ Calculate and assign to the variables areal, area$2,$ circl and circ$2$ the area and circumference of cach circle. Use Math.PI in your calculations. Be sure to label and format each output value properly as shown below. Align the $"="$ signs in eolumn $24.$ Remember to label all seetions and elose the input object.

Data File Input $("$lab$3$B$3,$in$")$:

$10\mathrm{.}03\mathrm{.}5$

Expected output:

$+******,**************************$

Radius $=10\mathrm{.}0$

Area $=314\mathrm{.}2$

Circumference $=62\mathrm{.}8$

$************************************$

Radius $=3\mathrm{.}5$

Area $=38\mathrm{.}5$

Circumference $=22\mathrm{.}0$
