7

X r

__ = 88 x 7

2 x 22

r = __ cm

Area of the circle = ___

= 22

7

x ___ x 14

= ______ sq cm .

Area of the circle is ____ sq cm .​

Answer 1

Answer:

616 sq cm

Step-by-step explanation:

circumference of circle= 2×22/7 × r

88= 2 × 22/7 xR

88/2= 22/7×R

44×7=22×R

308/22 =R

14 =Radius

area of circle = 22/7 ×R^2

= 22/7 ×14^2

=22/7 × 196

=22 × 28

= 616 sq cm
