let me try and help
Ok if the angle for the circle is 360 and then it is split into 8 parts than that means that the central angle is 360/8 which is?

Ok then the arc length is a fraction of the circle's total circumference so you would after you find the central angle find the circumference of the whole thing and then multiply by 45/360=1/8
crispyrat:
C = 2*pi*r<--circumfrence area by the way
hamidiso23:
yup
crispyrat:
then you find the area of the whole pizza and then multiply it by 45*2/360=90/360=1/4

@AZ is this right?
snowflake0531:
Arc length formula \(2 \pi r(\frac{\theta}{360})\)
\(2\pi(6)(\frac{45}{360})\)
snowflake0531:
c. \(\frac{1}{2}{\pi r^2}\)
\(\frac{1}{2}\pi (6^2))\)
hamidiso23:
so whats the answer
hamidiso23:
1/4
