LuckyWell [14K]

Answer:

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = 2(L + W)

Where

L represents the length of the rectangle.

W represents the width of the rectangle.

A proper rectangle has a length of 6 inches and a with of 8 inches. The area of the rectangle would be

6 × 8 = 48 inches^2

A square with a side length of 3 inches was cut of it. The formula for determining the area of a square is l^2

Therefore,

Area of square = 3^2 = 9 inches ^2

The area of the remaining paper would be

48 - 9 = 39 inches^2

Bond [772]

Answer:

B

Step-by-step explanation:

We can notice that based on the given pattern, the average rate of change from x=n to x=n+1, where n \in \mathbb{Z}, is -2n-1.

So, the average rate of change from x=8 to x=9 is -2(8)-1=-17.

What is the area of a sector with a central angle of 8 π/11 radians and a radius of 7.2 ft? use 3.14 for π and round your final
coldgirl [10]

Answer:

59.19 ft^2

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

A=\pi r^{2}

we have

r=7.2\ ft

\pi =3.14

substitute

A=(3.14)(7.2)^{2}

A=162.78\ ft^2

step 2

we know that

The area of a circle subtends a central angle of 2π radians

so

using proportion

Find out the area of a sector with a central angle of 8 π/11 radians

\frac{162.78}{2\pi }\frac{ft^2}{rad} =\frac{x}{(8\pi/11)}\frac{ft^2}{rad} \\\\x=162.78(8/11)/2\\\\x=59.19\ ft^2
