Question

circumference =15 CM what is the diameter and radius​

Answer 1

Answer:

Step-by-step explanation:

Circumference of a Circle = 2πr

2×22/7×r = 15 cm

r = 15×22/2×7

r = 165/7

Answer 2

Answer:

Step-by-step explanation:

circumference=2payR

15=2x22/7xR

15=44/7R

44/7R=15

R=15X7/44

=105/44

=2.38(APPOREX)

when R=2.38

therefore,d=2xR

                  =2x2.38

                  =4.76
