Answer:
x=30
Step-by-step explanation:
area of Arc subtending
(i.e. the whole circle) is $\pi r^2$
so area of Arc subtending $\theta^{\circ}$ is, $\frac{ \pi r^2}{360^{\circ}}\times \theta^{\circ}$
$\theta =72^{\circ}$ so the area enclosed by one such arc is $\frac{\pi (10)^272}{360}$
abd there are 2 such arcs, so double the area.
Answer:
d
Step-by-step explanation:
Try using simple numbers like 1 as x and then try with the different functions until it works
