Find the radius of the field?
plz answer fast​

Answer 1

Answer:

52820/24 2200.833=22/7 * r2

Step-by-step explanation:

r2 =700 r= 26 approx

Answer 2

Answer:

Length of the fance in (meters)=total cost/rate=5280/24=220

So,circumference of the field=220m

Therefore,if r meter is radius of the field,then2Πr =220

or,2×22/7×r=220

or,r=(220×7)/(2×22)=35

radius of the field is =35m

Therefore,area of the field =2Πr=22/7×35×35m²=22×5×35m²

Now,cost of plugging 1m²the field =RS=0.50

So total cost of plugging the field =Rs22×5×35×0.50=Rs 1925
