Question

20) 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

Answer:

$\huge\color{red}\underline{Answer↓}$

49cm

Step-by-step explanation:

$\huge\color{red}\underline{Given,}$

Circumference of the round plate = 145 cm

$\huge\color{red}\underline{To \:find,}$

Diameter of the round plate

$\huge\color{red}\underline{Procedure,}$

Since,

$circumference = \pi d$

$diameter = \frac{ 145}{ \pi} \\ = \frac{145}{3.14}$

$= 46.2(approx.)$

Since, from the available options, 49 cm is nearest to the approximation, therefore, 49 cm is the correct option
