Question

A and S are on circle D. 3434 Divided by 4

Answer 1

\[area = \frac{ \theta r^{2} }{ 2 }\] make sure theta is in radians though

another way is just to take a ratio like

118 degrees / 360 degrees = area of sector / area of circle so

\[\frac{ 118 }{ 360 } = \frac{ sector }{ \pi r^{2} }\]

Answer 2

so I divide that?

Answer 3

yeah, take 118/360, then multiply that by pi r^2

Answer 4

a?

Answer 5

i get d

Answer 6

\[\frac{ 118 }{ 360 } = \frac{ x }{ \pi * 13^{2} }\]

Answer 7

Ohhh ok I see now
