Salma runs 7 rounds of a circular field and covered a distance of 5.6 km. Find the diameter of the field (upto 3 decimal places) if perimeter is 3.14 times the diameter.

Open in App

Solution

Distance Salma covers running 7 rounds = 5.6 km
Distance covered in one round = $5.6 \div 7 km = 0.8 km$ Therefore, perimeter = 0.8 km

Given, perimeter = 3.14 $\times$ diameter.
Therefore, diameter = $perimeter \div 3.14$
Diameter = $0.8 \div 3.14 = 0.254 km$
Therefore, diameter of the firld is 0.254 km or 254 m.

Distance Salma covers running 7 rounds = 5.6 km Distance covered in one round = 5.6 ÷ 7 km = 0.8 kmTherefore, perimeter = 0.8 km Given, perimeter = 3.14 × diameter. Therefore, diameter = perimeter ÷ 3.14 Diameter = 0.8 ÷ 3.14 = 0.254 km Therefore, diameter of the firld is 0.254 km or 254 m.
