Question

find the circumference of a circle whose radius is 10 .5​

Answer 1

2πr=2×22/7×10.5

=44/7×10.5

=44/7×10.5/1×10/10=150/10

=44/7×150/10

= 6600/70......,

l hope the ans helps you.....,

please mark it as brilliant answer......,

thank-you

Answer 2

$\large \bold{ \underline{ \underline{ \sf \: Answer : \: \: }}}$

$\to$ Circumference = 65.94 cm

$\large \bold{ \underline{ \underline{ \sf \: Explaination : \: \: }}}$

Given ,

$\star$ Radius = 10.5 cm

We know that ,

$\large\fbox{ \fbox{\sf \: \: circumference \: of \: circle = 2 \pi r \: \: }}$

$\to \sf \: Circumference = 2 × 3.14 × 10.5 \\ \\ \to</p><p> \sf Circumference = 65.94 \: cm$

$\therefore$ Circumference of the circle is 65.94 cm
