Question

find the radius of a circle if its area is 25 pi cmsq​

Answer 1

Answer:

radius = 5 cm

Step-by-step explanation:

we know that area of circle is πr^2

so

πr^2 = 25π cm^2

r^2 =25

r =5 cm

Answer 2

1. we know area of circle is pi×r^2 so pi×r^2=25 hence r^2=25/pi hence r^2=25/22/7 hence r^2=175/22 therefore r^2=7.95 approx 8 and so r=√8 so radius of circle is √8 cm
