Question

if the area of a circle is 616 cm square find its diametre​

Answer 1

Area of a circle = $\pi r^2$, where r is the radius of the circle

Given: area is 616 cm²

Hence

$\pi r^2=616$

$r^2*\frac{22}{7}=616$

$r^2=\frac{616*7}{22}$

$r^2=196$

$r^2=14^2$

Hence radius is 14 cm

Hence diameter = $2r =28$ cm

Hence the answer is 28 cm

HOPE THIS HELPS!!

Answer 2

Answer:

88 cm^2 is the answer
