Question 7
Area of a circle is 616 square cm. The circle is surrounded by a path 2 meter wide. What is the area of this path ?

Answer 1

if area of circle is 616cm square then it's radius is

616=22/7*rsquare

so rsqaure=616*7/22

r=14

now path is of 2cm so r=14+2=16

so area =22/7*16*16

r=804.57

now to find area of path

area =804.57-616

=188.57

answer=188.57
