Question

the area of a circle is 132cm . find its diameter

Answer 1

Answer:

Step-by-step explanation of:

Area of circle=πr^2

132=πr^2

r^2=132×7/22

=42

r=√42

Diameter=2r

=2√42

Answer 2

Answer: 12.96cm

Area of circle =$\pi$$r^{2}$

132=$\pi$r^2

r^2 = 42cm

r= $\sqrt{42}$

Diameter=2r =2√42

∴ Diameter = 12.96cm
