Step-by-step explanation:

r≈3.5m

C Circumference

Using the formula

C=2πr

Solving forr

r=C

2π=22

2·π≈3.50141m

Approximately

3.5

Explanation:

The circumference of a circle C is equal to:

⋅

That's because the diameter of a circle fits

times in the circumference. So if you solve

⋅

≈

3.5

(using the approximation

≈

)

Answer:

3.5 cm

Step-by-step explanation:

Using the formula

c=2πr

Answer: <

Explantion:

$8*4-2(4)=24$

$5(10-4)=30$ , because you factor the 5 into 10 and 4 so

$50-20=30$

The second one you want will be integers.

What is the slope of the line between (−4, 4) and (−1, −2)? a. 1 b. 2 c.−2 d. −1

Vikki [24]

M= $\frac{ Y_{2}- Y_{1} }{X_{2}-X_{1}}$

m= (-2 - 4) / (-1 - -4)
m= -6 / (-1 + 4)
m= -6 / 3
m= -2

the slope is -2 (C.)

the vertices of triangle PQR are P(-3, 8), Q(-6, -4), and R(1, 1). If you reflect triangle PQR across the x-axis, what will be t

otez555 [7]

Answer:

The coordinates of the vertices of the image will be:

P'=(-3,-8)

Q'=(-6,4)

R'=(1,-1)

Step-by-step explanation:

If you reflect a point P=(x,y) across the x-axis, the coordinates of the image will be P'=(x,-y), then:

P=(-3,8)=(xp,yp)→xp=-3, yp=8→P'=(xp,-yp)→P'=(-3,-8)

Q=(-6,-4)=(xq,yq)→xq=-6, yq=-4→Q'=(xq,-yq)=(-6,-(-4))→Q'=(-6,4)

R=(1,1)=(xr,yr)→xr=1, yr=1→R'=(xr,-yr)→R'=(1,-1)
