Question

) एका वर्तुळाचा परीघ 62.8 सेमी आहे, तर त्याची त्रिज्या व व्यास काढा. (TT = 3.14) (The circumference of a circle is 62.8 cm. Find its radious and diameter.) (11 = 3.14)​

Answer 1

Answer:

Radius = 10cm

Diameter = 20cm

Step-by-step explanation:

circumference = 62.8

circumference = 2πr

62.8 = 2 X 3.14 X r

62.8 = 6.28 X r

$r = \frac{62.8}{6.28} = \frac{628 \times 100}{628 \times 10} \\ r = 10$

Radius = 10cm

Diameter = 2r = 2 X 10 = 20cm
