Question

if radius is 7 cm then what is its diameter and circumference ​

Answer 1

Radius= 7cm

Diameter = 2r = 2×7 = 14cm

Circumference = 2πr

= 2×22/7×7

= 2×22×1

= 44cm

Answer 2

Answer:

DIAMETER:14 CM

CIRCUMFERENCE:44 CM

Step-by-step explanation:

DIAMETER OF CIRCLE = (RADIUS)*2

                                      =(7)*2

                                       =14

CIRCUMFERENCE: 2πR

                               :2×22/7*7

                               :2*22

                               :44 CM
