HELP ME! Area within central angle AOB is ____ (pii) square units. Area central angle AOB less triangle AOB = _________pii - _______ sqrt of_______square units
@jim_thompson5910 i dont wanna bother but please help me with these last questions please
what is number one asking?
It looks like you're first finding the area of the circular pie shaped (or pizza sliced shaped) region
Then you're finding the area of the triangle Finally, you're subtracting the two areas
ohhhh ok:D
Area of circular pie shaped piece A = (angle/360)*pi*r^2 A = (60/360)*pi*6^2 A = (1/6)*pi*36 A = 6pi So the area of the circular pie shaped piece is exactly 6pi square units
i really didnt understand, thanks!
ohhhh you use that formula
do you see how I got the area of the pie shaped piece?
yes!
alright great
Area of the triangle This is an equilateral triangle, so you use the formula A = (s^2*sqrt(3))/4 A = (6^2*sqrt(3))/4 A = (36*sqrt(3))/4 A = 9*sqrt(3) So the area of the triangle is exactly 9*sqrt(3) square units.
Now subtract the two to get the last answer 6pi - 9*sqrt(3)
yay! thank you! you're the best tutor here!!!!!
you're welcome, lol thx for the compliment
