A manufacturer makes conical funnels for professional painters. The
funnels are formed from plastic with an 8-inch diameter base and height
of 9 inches. After the cones cool, a machine cuts off 1 inch of the tip to
leave a 1-inch diameter hole in the end. What is the volume of the funnel?
Round your answer to the nearest tenth and do NOT include units.

Step-by-step explanation:

In this situation we have two cones, the big cone with volume and the small cone with volume .

Now, if we want to know the total volume we have to substract from  , but first we have to calculate each volume:  

For the big cone:

Where:

Then:

Volume of big cone

For the small cone:

Where:

Then:

Volume of small cone

Calculating the total volume:

Finally:

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

y=1/4x-4
