Question

the area of circle 140m2 radius and circumference ??

Answer 1

HI!

HERE IZ UR ANSWER.

Area of circle = πr^2

As given in question

πr^2 = 140m^2

r^2 = 140/π
r^2 = 440
r = √440
r = 21 cm.

circumference of circle = 2πr
= 2 × 22/7 × 21
= 2 × 22 × 3
= 44 × 3
= 132 cm.

So, radius is 21 cm and circumference is 132 cm.
