Question

Draw a flowchart to find the area of circle

Answer 1

Area of circle :-
$\pi r ^{2}$
In this pie is taken as 22/7 and 'r' is the radius.

Example :- Find out the area of a circle with radius 5m.
Solution :- 22/7×5×5
(In this 5 is the radius which has the power 2)

22/7×25
= 78.5m

Answer 2

• Area of circle
- 2πr
here π=22/7 and r=radius of circle.
E.g.- find area of circle radius is 14cm.
sol- r= 14cm
Area of circle = 2×22/7 ×14
44/7×14
44×2
88 cm.
