Answer:
The correct option is C
Step-by-step explanation:
Given the circumference of circle which is 54 cm and also the measure of arc XY is 120°
we have to find the expression for arc length of XY
The arc length can be calculated by the formula
![\frac{\theta}{360}\times 2\pi r](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctheta%7D%7B360%7D%5Ctimes%202%5Cpi%20r)
![\frac{\theta}{360}\times circumference](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctheta%7D%7B360%7D%5Ctimes%20circumference)
![\frac{120}{360}\times 54](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B360%7D%5Ctimes%2054)
Hence, option C is correct
Answer:
He would make $36 for 12 pounds of strawberries
He would make $196 for 49 pounds of blueberries
He would make 3S if he sold S pounds of strawberries
He would make 4B if he sold B pounds of blueberries
Working:
We know that strawberries are $3/pound so $3 x 12pounds = $36
We know that blueberries are $4/pound so $4 x 49pounds = $196
The letters represent the amount of pounds of fruit being bought so the calculation for that is ($ x pounds) so you would write this but without assigning a numerical value to the amount. So if the strawberries are $3/pound and Luke sold ‘s’ pounds then it would be 3S (or 3xS but that is already assumed). The same goes for the blueberries. We know that they are $4/pound so it would be 4B.
Sorry if this doesn’t make any sense but I hope this helped
