The radius of a circular box is 21 centimeters. What is the circumference of the box? A 66cm B 132cm C 176cm D 1386cm

Ulleksa [173]

The answer would be 132 because the formula for find circumference while using radius is 2(3.14)r .

C= 2(3.13)21

C= 6.28 • 21 = 131.88

131.88 rounded is 132

see the attached figure to better understand the problem

we know that

In the right triangle ABF

Applying Pythagoras Theorem

$A.F^{2}=6.5^{2}-6^{2}$

$A.F^{2}=6.25$

$A.F=2.5\ cm$

In the right triangle CED

$CE=6\ cm$

$ED=23-(9+2.5)=11.5\ cm$

$tan($

substitute the values

$tan($
