Hi Ashley. c: Long time no speak.

OpenStudy (ashleyisakitty):

Hai :3 Do you have the answer choices by chance? like a b c d? or do you have to type it in?

OpenStudy (anonymous):

No, sadly, I don't. /:

OpenStudy (anonymous):

area of a sector of a circle is\[\frac{ degrees }{ 360 } \times \pi r^2\] where degrees is the number of degrees in the central angle of the sector

OpenStudy (ashleyisakitty):

Grrr... I honestly dont remember how to do this. I plugged what i believed were the calculations and got 26 for the first one and 500 for the second one which doeeesnt sound right .-.

OpenStudy (anonymous):

62/360(πr^2) Would be the first one?

OpenStudy (anonymous):

yes

jimthompson5910 (jim_thompson5910):

replace r with 7 since you know the radius is 7

OpenStudy (anonymous):

19. 26.51 20. 500.69 Would that be correct?

jimthompson5910 (jim_thompson5910):

both are correct, nice work

OpenStudy (anonymous):

Thanks!

OpenStudy (ashleyisakitty):
