Circumference of circle = 2×π×r
35.2 cm =2×22/7×r
35.2 =44r / 7
r=5.6 cm
Area of circle = /πr×r
=22/7 × (5.6) × (5.6)
=98.56
35.2 cm =2×22/7×r
35.2 =44r / 7
r=5.6 cm
Area of circle = /πr×r
=22/7 × (5.6) × (5.6)
=98.56
goswamiadityaraj:
where comes from 5.6
we need to find r first ... see again
and u asked for r ...
in your question
ya
i am not understanding
say
if we did not find the radius ,then we did not get the area of circle

Circumference = 35.2m
Circumference = 2πr
35.2 = 2 x π x r
Solving it r = 5.6m
Area = πr2
Solving it we get area = 98.56m2
Hope it helps......
