Diameter of a circular park is 28m then find the distance covers in 5 roundsrounds- About the author Sadie
Answer: Answer As the garden is in the shape of circle. Therefore, Diameter of garden =28m(Given) ⇒ Radius of garden (r)= 2 28 =14m As we know that circumference of the circle is given by- Circumference =2πr where as, r is the radius of circle. Therefore, Circumference of garden =2× 7 22 ×14=88m For 3 rounf of fence, Length of wire required =3×88=264m Given that the cost of wire is Rs.30 per m Therefore, Cost of wire =30×264=Rs.792. Hence the length of wire required is 264m and the cost of required wire will be Rs.792. Reply
Answer:
28×5=140
Step-by-step explanation:
140m the distance covered in 5 round.
Answer:
Answer
As the garden is in the shape of circle.
Therefore,
Diameter of garden =28m(Given)
⇒ Radius of garden (r)=
2
28
=14m
As we know that circumference of the circle is given by-
Circumference =2πr
where as, r is the radius of circle.
Therefore,
Circumference of garden =2×
7
22
×14=88m
For 3 rounf of fence,
Length of wire required =3×88=264m
Given that the cost of wire is Rs.30 per m
Therefore,
Cost of wire =30×264=Rs.792.
Hence the length of wire required is 264m and the cost of required wire will be Rs.792.
