Answer:

A = 121π in²

Step-by-step explanation:

The circumference (C) of a circle is

C = 2πr ( r is the radius )

Here C = 22π , that is

2πr = 22π ( divide both sides by 2π )

r = \frac{22\pi }{2\pi } = 11

The area (A) of a circle is

A = πr² = π × 11² = 121π in²

Find the value of \mathrm{x}xin the following figure.
Hoochie [10]

Step-by-step explanation:

step 1. I guess we assumed the two lines across the transversal are parallel

step 2. 3x + 1 = 85 (definition of alternate exterior angles)

step 3. 3x = 84 (subtract 1 from each side)

step 4. x = 28. (divide both sides by 3)

What is the equation of the function that is graphed as line a?
Andrei [34K]

Answer:

B

Step-by-step explanation:

We see that the line intersects the y-axis at -1.  As a result, we need to choose an equation with -1, either B or C.  We see that the different is the slope.  For choice B, the slope is \frac{1}{3}, meaning that every unit up equates to 3 blocks to the right.  Counting along the line, we see that this is correct.

First question: 2x = 50
Explanation:
“2 times as many” in this situation means that the pages justin read (50) is twice as Colin’s. Meaning that to find the number of pages Colin’s read, we will have to divide 50 by 2.
2x = 50 is an equivalent representation of that.

A walkway surrounds a rectangular garden. The width of the garden is 3 meters, and the length
rusak2 [61]

Answer:

You are given the width of the garden which is w= 8 feet

length of the garden which l= 6 feet

the width of the walkway is x

so for every side of the garden there is an x

so length overall would be 8+2x (length of garden + x one side + x other side)

and width overall would be 6 + 2x (width of garden + x of one side + x of other side)

area of rectangle is length*width

so the expression would be (8+2x)*(6+2x)

:))) smile....

I hope it is correct.
