Answer:
[Refer The Attachment ]
Formula used =
↪Area of circle = πr^2
EXPLANATION =
⚫let,
↪Radius of small circle (r1)=7m
↪Radius of large circle (r2) =8.75
now,
Area of small circle =π(r1)^2
=22/7x(7)^2
=154
Area of large circle =π(r2)^2
=240.62
↪AREA enclosed = Area of large circle -area of small circle
= 240.62-154
= 86.62
➡therefor area enclosed between two concentric circles is 86.62
Answer:
86.62
Step-by-step explanation:
↪Radius of small circle (r1)=7m
↪Radius of large circle (r2) =8.75
now,
Area of small circle =π(r1)^2
=22/7x(7)^2
=154
Area of large circle =π(r2)^2
=240.62
↪AREA enclosed = Area of large circle -area of small circle
= 240.62-154
= 86.62
➡therefor area enclosed between two concentric circles is 86.62
