Question

the adjoining figure shows a racing track consisting of two parallel stretches which is 119 M long and 10 metre wide its other two end are semicircular the inner distance between the two parallel Streches is 70 m evaluate and also find the distance around the track along its outer edge and the area of the track

Answer 1

Answer:

Step-by-step explanation:

The track is in shape of two circles with same centre

The distance around the track along its outer edge will be

Diameter of inner circle + 2× width of track

= 70m + 2 × 10m

= 90m

Area of track = Area of outer circle -

Area of inner circle

= 22/7 ×R square - 22/7 × r square

= 6364 - 3850

= 2514 m square

Answer 2

Answer:

The track is in shape of two circles with same centre

The distance around the track along its outer edge will be

Diameter of inner circle + 2× width of track

= 70m + 2 × 10m

= 90m

Area of track = Area of outer circle -

Area of inner circle

= 22/7 ×R square - 22/7 × r square

= 6364 - 3850

= 2514 m square
