So it would be 12 minutes and $5 per 12 minutes.
Answer:
942 6/7 cm²
Step-by-step explanation:
Since O = Center of bigger circle, OA = Radius of bigger circle.
∴ Area of smaller circle - Area of bigger circle = Area of shaded part.
∴ Area of smaller circle = 22/7 × 10²
= 22/7 × 100
= 2200/7
= 314 2/7 cm²
∴ Area of bigger circle = 22/7 × 20 ²
= 22/7 × 400
= 1257 1/7 cm²
∴ Area of shaded part = 1257 1/7 - 314 2/7
= 942 6/7 cm²
The formula for the volume of a cone is V=(1/3)πr^2h. Plugging in what you know, you get (1/18)π=(1/3)π(1/3)^2(h). The radius is half the diameter 2/3 so it is 1/3. Simplifying, you get (1/18)π=(1/3)π(1/9)(h) which is (1/18)π=(1/27)π(h). Dividing both sides by (1/27)π, you get h=1.5ft.

Answer:
The class in the second and longest bar graph (the one labeled 3) has the most students.
Step-by-step explanation:
When looking for the largest amount of something in bar graphs, the largest bar graph is correct. In this case the second bar graph is the longest, and we can see it indicates the class contains 28 students.
X = 180 -30
x = 150
