Question

A round plate has a circumference of 145 cm. Among the diameters 57 cm, 24 cm, 49 cm and 145 cm, which could be that of the smallest box in which the plate could be packed?

Answer 1

We find radius first
C=pie d
145=(22/7)d
d=46.13
Ans:49

Answer 2

Step-by-step explanation:

C= 2πr =145/πd

22/7×57=179.142

22/7×24= 75.428

22/7×49=154cm

22/7×145=455.714

Diameters 145cm could be that of the smallest box in which the plate could be packed
