Answer:
24/5
Step-by-step explanation:
The way I think about areas of sectors is a fraction of the pie. You know what percentage of the "pie" (in this case, circle) you want, because they give you the angle of the sector and you know a circle always has 360°. So technically, you're trying to find 48/360 th of the entire area (36). If you're using a calculator, it doesn't matter if you simplify the fraction, but if you're doing it by hand simplifying makes everything a lot easier.
The equation will be:
Area = 24/180 × 36
= 2/15 × 36
= 72/15
= 24/5

Answer:
See screenshot below
Step-by-step explanation:
Yes Bus Column:
- We need to find an answer for the "no taxi" section. And we have the total and the "yes taxi" section. So, the "yes taxi" section + the "no taxi" section gives you the total. Another way of saying this is total - "yes taxi" = "no taxi"
- 125 - 30 = 95
No Bus Column:
- We need to find the total of the "yes taxi" section and the "no taxi" section. So, if we add those two sections together, we'll get the total
- 90 + 185 = 275
Total column:
- So, this column is really simple to fill out. All we're doing it adding our answers above to get one answer in each section.
- "Yes Taxi" section: 30 + 90 = 120
- "No Taxi" section: 280
- Total section: 125 + 275 = 400
- We could have also done the total section by adding together 120 and 280, but we would get the same answer, anyway.
I hope this helps!
