PLEASE HELP!!! Would you rather paint 3/4 of a circle or a circular ring? Using area, explain your reasoning. Include calculatio
Nostrana [21]

Answer: I would paint either of the 3/4 of a circle or a circular ring.

Step-by-step explanation: We shall start by calling the three quarter circle on the left A, and the ring on the right we shall call B.

The area of both can be calculated and that figure which results in the lesser value (of area) shall cost you less to paint.

For A, the area of the circle is given as

Area = πr²

Where π shall be taken as 3.14 and the radius r is 6.

Area = 3.14 * 6²

Area = 3.14 * 36

Area = 113.04

The area of the quarter of the circle would be subtracted from the total area as shown in the calculation above.

Area of sector = ∅/360 * πr²

The sector is a quarter of the circle and that makes the angle at the sector to be equal to (360/4) 90 degrees. Therefore ∅ equals 90.

Area of sector = (90/360) * 113.04

Area of sector = 1/4 * 113.04

Area of sector = 28.26

Area of A therefore is derived as;

Area of A = 113.04 - 28.26

Area of A = 84.78 square metres

For B, the area of the ring is given as follows;

Area of B = Area of larger circle - Area of smaller circle

Area of B = πR² - πr²

Where R is the radius of the larger circle and r is the radius of the smaller inner circle. By factorizing the right hand side of the equation, we now have;

Area of B = π (R² - r²)

Area of B = 3.14 (6² - 3²)

Area of B = 3.14 (36 - 9)

Area of B = 3.14 * 27

Area of B = 84.78 square metres.

From the calculations shown along with the explanations, both the three-quarters and the ring have exactly the same area, which means you are going to spend exactly the same quantity of paint and spend the same amount of time painting either one of them.

So the answer is; I would paint EITHER ONE OF THEM.

Graph each circle given below right the center and radius of each circle
expeople1 [14]

Answer:

Center: (-3,-2)

Radius: √6

The graph is attached.

Step-by-step explanation:

The equation of the circle has the form:

(x -h)^{2}+(y-k)^{2}=r^{2}

Where (h,k) is the  point of the center of the circle and r is the radius of the circle.

The equation given in the problem is

(x +3)^{2}+(y+2)^{2}=6

 Therefore:

h=-3

k=-2

The center is at (-3,-2)

And the radius is:

r^2=6\\r=\sqrt{6}

Then, you can graph it has you can see in the image attached.

The graph shows the height h, in feet, of s football at time t, in seconds, from the moment it was kicked at ground level. Estim
aliina [53]

The graph shows the height h, in feet, of s football at time t, in seconds, from the moment it was kicked at ground level.

We are supposed to find the average rate of change in height from t=1.5 seconds to t=1.75 seconds.

Average rate of change in height=\frac{\text{Change in Height}}{\text{Time taken}}\\

As we can see from the the change in distance for the time interval 1.5 second to 1.75 second=12-7=5

and time=1.75-1.5=0.25

Average rate of change in height=\frac{5}{0.25}\\=20ft/sec

Hence Required Rate of change is -20 ft/sec, because its falling(In the direction of negative y-aixs)
