Suppose a slice of a 10-inch pizza has an area of 15 square inches. What is the angle of this slice?
1 answer:
Angleslice/360 times area=area of slice area=pir^2 normally pizzas are given in terms of ther diameter so 10=diameter d/2=r, 10/2=5 r=5 area=pi5^2=25pi angleslize/360 times 25pi=15 do math times 360 both sides and divide by 25pi both sides angle=68.7549 degrees or 1.2 radians

Answer:
60 starbursts
Step-by-step explanation:
We can set up an equation to find the answer. 21/x=0.35/1 because we're trying to find how many starbursts make up 100% of the package. So then to solve, we take 21x1 and then divide that by 0.35. From this we find that x=60.
