Question

write a python code to accept the redius of a cirle and calculate the are and perimeter of a circle​

Answer 1

Python: Area of a Circle

In geometry, the area enclosed by a circle of radius r is πr2. Here the Greek letter π represents a constant, approximately equal to 3.14159, which is equal to the ratio of the circumference of any circle to its diameter.

Python: Area of a circle

Sample Solution:-

Python Code:

from math import pi

r = float(input ("Input the radius of the circle : "))

print ("The area of the

Answer 2

$\bf \underline {CODE}$

$\sf \green {import} \: math$

$\sf R \pink{=} \green{eval}(\green{input}( \red{"Enter \: the \: radius \: : \: " }))$

$\sf \green{print}(\red{"The \: Perimeter \: of \: circle \: is \: : "\:} ,\green{2} ^{*} (math.\blue{pi}) ^{* } R,\red{"units"})$

$\sf \green{print}(\red{"The \: Area \: of \: circle \: is \: : "\:} ,(math.\blue{pi}) ^{*} R ^{ **}\green{2},\red{"sq \: units"})$

$\bf \underline{OUTPUT}$

$\sf Enter \: the \: radius \: : \:24$

$\sf The \: Perimeter \: of \: circle \: is \: : \: 150.79644737231007 \: units$

$\sf The \: Area \: of \: circle \: is \: : \: 1809.5573684677208 \: sq \: units$
