Question

the circumference of circle is 88 cm. Find area

Answer 1

C = 2 pi r = pi d ( d = 2r) 
A = pi r^2 

88 = 2 pi r 
r = 88/2pi = 44/pi 
r^2 = (44/pi)^2 
A = pi ( 44/pi)^2 
A = pi 44^2 / pi^2 
A = 44^2 / pi 
A = 44 X 44 / 3.141592.... 
A = 616.247.... cm^2

Hope this helps u..

Answer 2

circumference=88 cm.
2$\pi$r=88
$\pi$r=44
r=44 × 7/ 22
r=2 × 7= 14 cm.
radius= 14 cm.

area = $\pi$r²
        =22/7 × 14 × 14
        = 616 cm².

hope this helps
