Question

Find the radius of the circle whose circumference is 46.2 (Take pi=3.14)


​

Answer 1

Answer:

I hope it will help you

Circumference = 2*pi*r

3.14 = 2*3.14*r

2r = 1

r = 1/2 = 0.5 cm

Radius is 0.5 cm.

★ Given :

Circumference of circle is 46.2 cm².

____________________

★ To Find :

We have to find radius of the circle.

____________________

★ Solution :

We know that,

$\Large{\boxed{\boxed{\red{\sf{Circumference = 2 \pi r}}}}}$

(Putting Values)

$\sf{ \implies \: 46.2 = 2 \times 3.14 \times r} \\ \\ \sf{ \implies \: \frac{462}{ \cancel{10}} = 2 \times \frac{314}{10 \cancel0} \times r} \\ \\ \sf{ \implies \: 462 \times \frac{10}{314} \times \frac{1}{2} = r } \\ \\ \sf{ \implies \frac{ \cancel{4620}}{ \cancel{628}} = r} \\ \\ \sf{ \implies \: r = 7.35 \: cm}$

$\Large{\boxed{\boxed{\pink{\sf{Radius(r) \: = \: 7.35 \: cm}}}}}$
