A conical paper cup is 10 cm tall with a radius of 10 cm. The cup is being filled with water so that the water level rises at a rate of 4 cm/sec. At what rate is water being poured into the cup when the water level is 3 cm?

32cm³

Step-by-step explanation:

the volume of a cone is  

V

=

π

r

2

h

in this case, we can relate  

h

and  

r

as we know that the slope =  

h

r

=

we can make the volume a formula in a single variable

V

=

differentiating wrt time, it follows that

the answer is d on edge

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
