You have seen how to write, load, and run a program to calculate the
area of a circle from its radius. Now draw a flowchart and write a
function that will calculate the radius r of a circle given its
area A using the formula r = √(A/π). Be sure to set
the calculator to PRGM mode and press
GTO · ·
before you begin programming. Name the program with
g
LBL
ALPHA
RADIUS
ALPHA
and terminate it with END (use
GTO · · ).
After you have load the program, run it to calculate the radii of circles
with areas of 420 square inches, 1.2 square meters, and 0.9095 square meters.




(Answers: 11.5624 inches, 0.6180 meter, 0.5381 meter.)



2.

Write and load a program that will convert temperature in degrees
Celsius to degrees Fahrenheit, according to the formula
F = (1.8 × C) + 32. Name the program CTEMP and terminate it with
END . Convert Celsius of –40°,
0°, and 18°.




(Answers: –40.0000° F, 32.0000° F, 64.4000° F.)
