Question

measure of an Arc of a circle is 80° and its radius is 18 cm find the length of the arc if π is 3.14

Answer 1

hey mate

here is your answer

Answer 2

$Given \: Measure \: of \:an \:Arc \:of \:a \\circle (x) = 80\degree$

$Radius \: of \:the \:circle (r) = 18\:cm$

$Let \: length \:of \:the \:Arc = \red{l}$

$\pi = 3.14$

$\boxed {\pink { length \:of \:the \:Arc = \frac{x}{360} \times 2\pi r }}$

$l = \frac{80}{360} \times 2 \times 3.14 \times 18 \\= 8 \times 3.14 \\= 25.12 \:cm$

Therefore.,

$\red {length \:of \:the \:Arc} \green {= 25.12 \:cm}$
