Fig.12.26 depicts a racing track whose left and right ends are semicircular.The distance between the two inner parallel line segments is 60m and two are each 106m long.If the track is 10m wide,find : (i) the distance around the track along its inner edge (ii) the area of the track.

The given figure depicts a racing track whose right and left ends are semicircular. The distance between the two inner parallel line segments is 60m and they are each 106m long. If the track is 10m wide.(i) the distance around the track along its inner edge (ii) The area of the track. Running should be made compulsory for students, give your opinion.

The inside perimeter of a practice running track with semicircular ends and straight parallel sides is 312 m. The length of the straight portion of the track is 90 m. If the track has a uniform width of 2 m throughout, find its area.

Two parallel rails of a railway track insulated from each other and with the ground are connected to a millivoltmeter. The distance between the rails is one metre. A train is traveling with a velocity of 72 km ph along the track. The reading of the millivoltmetre (in m V ) is : (Vertical component of the earth's magnetic induction is 2 xx 10^(-5) T )

The inner perimeter of a running track (shown in figure) is 400 m. The length of each of the straight portion is 90 m and the ends are semicircular. If the track is everywhere 14 m wide, find the area of the track. Also, find the length of the outer running track.

Following figure depicts a park where two opposite sides are parallel and left and right ends are semi-circular in shape. It has a 7 m wide track for walking. Two friends Seema and Meena went to the park. Meena said that area of the track is 4066 m^2 . Is she right? Explain.

The inside perimeter of a running track (shown in figure) is 400m. The length of each of the straight portion is 90m and the ends are semi-circles. If the track is everywhere 14m wide, find the area of the track. Also find the length of the outer running track.

A race track is in the form of a ring whose inner circumference is 352 m and the outer circumference is 396 m. Find the width of the track.

A running track has 2 semicircular ends of radius 63 m and two straight lengths. The perimeter of the track is 1000 m. Find each straight length.

The inner circumference of a 7 m wide circular race track, is 220 m. Find the radius of the outer circle.
