Step-by-step explanation:
Radius, r = 7 cm
Diameter, d = 2r = 2 × 7 = 14 cm
∴ Circumference, c = πd
= 227 × 14
= 22 × 2
= 44 cm

Step-by-step explanation:
(1)
Circumference−diameter=18
⇒2πr−2r=18
⇒2r(π−1)=18
⇒ r(3.14−1)=9
⇒ r(2.14)=9
⇒ r= 2.14
9
⇒ r=4.20 cm
Hence, radius of circle= 4.2 cm
(4.)
circumference =14cm
2πr=14
2×22/7×14
2×22×2=88cm
