Question

Find the circumference of a circle of radius 10.5 Cm.​

Answer 1

Step-by-step explanation:

$\large\orange{\boxed{\tt AnsweR }}$

Here "r" = 10.5 cm

$(105 \div 10)$

$21 \div 2 \: cm$

So, Circumference =

$(2 \times 22 \div 7 \times 21 \div 2)$

= 66 Cm.

Answer 2

$\boxed{\LARGE{\bold{\pink{\mathfrak{Answer}}}}}$

circumference of the circle is 66 cm approximately.

$\boxed{\LARGE{\bold{\blue{\mathfrak{solution}}}}}$

Given that,

Radius of the circle = 10.5 cm

To find,

Circumference of the circle

We know that,

Circumference of a circle = 2πr

∴ circumference of the circle = 2 × 3.14 × 10.5

$\large{\boxed{\purple{\mathsf{∴ circumference\:of\:the\:circle = 66\:cm}}}}$

∴ circumference of the circle is 66 cm approximately.
