Question

if area of circle is 154cm2 find its radius
​

Answer 1

area of a sqaure = πr^2 =154cm^2

=> r^2=154*7/22=7*6cm

=> r=7cm

Answer 2

Answer:

Ok

Step-by-step explanation:

Here,

Area(a)= 154cm^2

then

we know

area=πr²

or, 154= $\frac{22}{7}$*r²

or, 154*7=22r²

or, 1078=22r²

or, $\frac{1078}{22}$=r²

or, 49=r²

or, √49=r     (square becomes root when turned in another side)

So, Radius is 7 ans!!
