An engineer is planning a new water pipe installation. The circular pipe has a diameter of d=20cm.

Komok [63]

We know that
the area A of the circular cross section of the pipe is
A=pi*r²
D=20 cm------------- > r=D/2=20/2=10 cm
then
A=pi*10²=100*pi cm²

the answer is A=100*pi cm²

Give the rate in miles per hour. Round to the nearest tenth.<br> Rachel jogs 20 feet in 3 seconds.

Tanya [424]

Answer:

Rate of jogging is 4.6 miles per hour.

Step-by-step explanation:

Rachel jogs 20 feet in 3 seconds and we have to find the rate of jogging in miles per hour.

Since 1 feet = 0.000189394 miles

Therefore, 20 feet = 0.0037879 miles

Similarly, 1 second = $\frac{1}{3600}$ hour

Therefor, 3 seconds = $\frac{3}{3600}$

= $\frac{1}{1200}$ hours

Formula to calculate the rate = $\frac{\text{Total distance of jogging}}{\text{Time taken to cover the distance}}$

= $\frac{0.0037879}{\frac{1}{1200} }$

= 1200 × 0.0037879

= 4.545

≈ 4.6 miles per hour

Therefore, rate of jogging is 4.6 miles per hour.

In the equation 6x-2-4x+ 2, Spencer claims that

Leona [35]

Answer:

Jeremiah is correct

Step-by-step explanation:

You did not put an equal sign so it's a bit confusing, but I was taught that whoever has lesser value (-4x) should be added/subtracted to both sides. (I think it's because -6x will make the equation worse). I'm so sorry if my answer is wrong btw. And congratulations if you did get it. I'm just answering based on what I was taught.
