Question

Inner circumference of a circular track is 264m and the width of the track is 7m. Calculate the area of the track

Answer 1

Inner Circumference of Track is 264 M
Outer Circumference of Track is 264 +7 = 271 M

Circumference of Track = 2 x pi x r
264 = 2 × 22/7 × r
(264x7)/2×22=r
1848/44 = r
42m= r

Area of Circle is = Pi rxr
=22/7×42×42
=5544 sq.m

Circumference of Track = 2 x pi x r
271= 2 × 22/7 × r
(271x7)/2×22=r
1897/44 = r
43.11m= r


Area of Circle is = Pi rxr
=22/7×43.11×43.11
=5841 sq.m

Area of Track is Outer-inner

5841-5544

297 sq meter
