Question

the circumference of a circular flower bed is 88cm and find its area

Answer 1

circumference of circle =2*pie*r
88=2*22/7*r
88=44/7*r
r=3.5
AREA of circle =pie*r*R
22/7*3.5*3.5=38.5

Answer 2

Area of the circle=
$\pi {r}^{2}$
but we don't know the lenght of radius so we find the radius

r= c÷2pie
= 88÷2×22/7
r = 14cm

so let's find the area

Area of circle = pie×r^2= 22/7×14^2

$\frac{22}{7} \times 196$
616cm^2

so the area = 616cm^2
