Answer:
the answer is a
Explanation:
formula= (angle / 360) x π x (diameter / 2)^2
i this case we have the radius already so
= (240/360)*(pi)*(11)^2
=2/3(3.14)*(121)
= around 253.29
= which leads me to believe a is correct
Solution given;
angle =240°
radius [r]=11cm
we have
length of arc =240°/360°×π*r²
=240°/360°×2×3.14*11²=253.29cm²
length of the arc is 253.29cm².
