It would be a parallelogram since if you look closely the individual shapes are indeed parallelograms.
Answer:
For a circle of radius R, the perimeter is:
P = 2*pi*R
Where pi = 3.14
If we have a section of this circle, defined by an angle θ, the length of that arc is calculated as:
L = (θ/360°)*2*pi*R
In this case, we have a unit circle, so the radius is 1 unit, and we have a section defined by an angle of 57°.
Then the total distance traveled will be equal to the length of the arc, which is:
L = (57°/360°)*2*3.14*(1 unit) = 0.99 units
Then the correct option is a.
(as we want to find the total distance, the starting point does not matter, so the total distance traveled in a section of 57° would be the same in any point of the circle, this means that the fact that we should start at the point (1,0) has no effect in this question)
Hi.
This is just simple division. We want to find miles per gallon, so we divide 675 by 45. You can use a calculator, but right now, I solved the problem. The answer is 15 gallons when the tank is full
Answer:
10 liters of orange juice, 5 liters of champagne
Step-by-step explanation:
We can call the amount of orange juice and champagne as x and 15 - x liters respectively. Then, we can write the following equation:
1.50 * x + 12 * (15 - x) = 5 * 15
1.5x + 180 - 12x = 75
-10.5x + 180 = 75
-10.5x = -105
x = 10 so 15 - x = 15 - 10 = 5.
1) Find the area of the circle: Ac = pi*(2 ft)^2 = 4pi ft^2
2) Multiply this result by 3/4: (3/4)(pi)(4ft^2) = 3 pi ft^2
3) Find the area of the square: As = (2 ft)^2 = 4 ft^2
4) Add together the results of steps (2) and (3): 3 pi + 4 ft^2 (answer)
