Answer:
1.Radius of circle =5cm
Circumference of circular sprinkled lawn=2πr
=2×22/7×5cm
=31.42cm
2.8cm
C = 2πr
= 2(3.14)(8)
=50.24
15cm.
r=15/2
=7.5
C=2πr
= 2(3.14)(7.5)
=47.1
50.24-47.1 =3.14
ans: 3.14
2.First bowl = C1
C= 2πr
C = 2π x 8
C= 50.27 cm
Second bowl = C2
C= πd
C = π x 15
C = 47.12 cm
How much greater is C1 to C2
C1 - C2 = answer
50.27 - 47.12 = 3.15cm
