Find the circumference of the circle shown. Round to the nearest tenth.

Sunny_sXe [5.5K]

Answer:

110 cm

Step-by-step explanation:

So if we know the diameter, which is 35 cm, we can use the formula π*d. So we would take the diameter and put it in the place of d. So it would be pie times 35. Which would result in us getting 109.96. And this rounded to the nearest tenth would be 110. So The circumference would be 110 cm.

If water flows through the pipe at a rate of 2L per seconds. How much water will pass through the pipe in 1/2hour

GenaCL600 [577]

Answer:

3600 Liters

Step-by-step explanation:

The given rate is 2L and we have to find how much water will flow in 1/2 hours at the same rate

1/2 hour is the same thing as 30 mins

multiply by 60 to convert minutes to seconds

$3omin * \frac{60sec}{1min} = 1800 s$

since the rate is 2L per second we multiply 1800 by 2 and get 3600 Liters
