caWrite a program that prompts the user for a radius and then prints

the diameter, circumference, and the area of a circle with that radius.

Use $3\mathrm{.}14159$ for the value of pi$.$

Hint: After your program gets the radius, convert it to a floating point using the float$()$

function.

Below is a sample run with Python output in blue and user input in black. The user should be

able to type any radius.

Enter radius:$2\mathrm{.}5$

Diameter $5\mathrm{.}0$

Circumference $15\mathrm{.}70795$

Area $19\mathrm{.}6349375$
