Answer:
Area = 95.4 cm²
Step-by-step explanation:
Given
θ = 135°
r = 9cm
Required
Calculate the area of the sector
Area of a sector is:
Area = θ/360 * πr²
Substitute values for θ and r
Area = 135/360 * π * 9²
Area = 0.375 * π * 81
Take π as 3.14
Area = 0.375 * 3.14 * 81
Are = 95.3775
Area = 95.4cm² ---- approximated
We are given the graph shows the cost of traveling by car on a turnpike.
Let us take two coordintes on the graph
(8,0.60) and (32,2.40)
We need to find the slope between those two points.
Therefore, slope for the given line is 0.075.

Hello there!</h3>
Let's look at all the information given to us.
- The tank can hold 13.5 gallons
- It is 2/3 full
And now the question it's asking.
- How many gallons to fill it?
Essentially, it's asking how to make the tank 100% full when it's already 2/3 of the way full.
To solve:
What fraction of the tank needs to be filled up?
100% is also equal to 3/3.
The difference between 2/3 and 100% therefore, can be rewritten as the difference between 3/3 and 2/3. Then it's clearer that the amount the tank needs to be filled is 1/3 of it's maximum capacity.
The maximum capacity is 13.5 gallons.
What's 1/3 of 13.5? To get that, multiply 1/3 by 13.5, to get 4.5.
Therefore, 4.5 is 1/3 of 13.5, and is therefore the amount of gasoline the tank needs to be filled up.
Your answer is 4.5 gallons.
