Question

the area of two concentric circle are 314 m square and 706 point 5 m square find the Radii of both the circle take π=3.14

Answer 1

Area of small circle = pir^2
Area=3.14×r^2=314
r^2=31400÷314
r^2=100
r=10cm
Area if larger circle =piR^2
Area=3.14×R^2=706.5
R^2=706.5÷3.14
R^2=225
R=15
HOPE IT HELPS!
Thankyou
