Question

The area of a circle is 616 cm². Find its circumference.

88
98
58
68

hint Hint:

$A equals pi r to the power of 2 end exponent$
Circumference = 2× $pi$ ×r

The correct answer is: 88

$A equals pi r to the power of 2 end exponent$
$fraction numerator 616 over denominator pi end fraction$ = $r to the power of 2 end exponent$
$r to the power of 2 end exponent$ = 196
R = 14
Circumference = 2× $pi$ ×r = 2×3.14×14 = 87.92 = 88
