Answer:

6\pi inches

Step-by-step explanation:

The area of a circle is \pi r^2.

Since \pi r^2=9\pi

r^2=9

And

r=3

Since the radius is 3 inches,

the diameter would then be 6 inches. (3 * 2)

The circumference of a circle is \pi d, d being the diameter.

Hence, the circumference is 6\pi.

Kanye and jay wanted to see who could run faster in a minute.They both started in the same spot and ran in different directions.
Lena [83]

Answer:

Kanye run faster.

Step-by-step explanation:

Given that,

Time = 1 min = 60 sec

Suppose, we find the speed of kanye and Jay.

According to number line,

Kanye covers the -160m distance and Jay covers the 140 m distance.

Negative sign shows the opposite direction.

We need to calculate the speed of Kanye

Using formula of speed

v=\dfrac{d}{t}

Where, v = speed

d = distance

t = time

Put the value into the formula

v=\dfrac{160}{60}

v=2.66\ m/s

We need to calculate the speed of Kanye

Using formula of speed

v=\dfrac{d}{t}

Put the value into the formula

v=\dfrac{140}{60}

v=2.33\ m/s

The speed of kanye is more than jay.

Hence, Kanye run faster.

What is the answer = 8w- 8 - 6w = 4w - 7<br> w= ??
ololo11 [35]

Answer:

<em>- 1/2     (or - 0.5) </em>

Step-by-step explanation:

so first, simplify by combining like terms.

so 8w-6w = 2w

so now we have

2w - 8 = 4w - 7

now we have to get the w's to one side of the equation so we can solve for it. so that mean we have to subtract 2w from both sides. 2w - 2w is 0. and then 4w - 2w = 2w. so now we have

-8 = 2w - 7

then to slowly start isolating w, add 7 to both sides of th equation. so now its

-1 = 2w

finally to get w by itself divide 2 from both sides.

and the answer is

-\frac{1}{2} = w

fiasKO [112]

Answer:

Step-by-step explanation:

Get the perimeter of the each shape and add it all up to get the total fencing material required.

2 square flower beds = 2 x 4a = 8a

1 rectangular play ground = 2l + 2w 

total fencing material = 8a + 2l + 2w
