Question

A race track is in the form of a ring whose inner cirumference is 220 m and outer circumference is 264 m . Find the area of the track .​

Answer 1

Answer:

1964m²

Step-by-step explanation:

given,

for inner circle 220=2πr

r1=220/2π=110×7/22=35m

for outer circle 264=2πr

r2=264/2π=264×7/2×22 =12×7/2=42m

Now,

area of inner circle =πr²=22/7×35×35

=22×5×35

=3850m²

area of outer circle =πr²=22/7×42×42

=22×6×42

=5544m²

Area of track = outer circle area-inner circle area

= 5544-3850 =1964m²
