Answer:

h = 5.705m

Step-by-step explanation:

Volume of a cylinder

V = πr^2h

V - volume of the cylinder

π - pie

r - radius of the cylinder

h - height of the cylinder

Given :

V = 363 cubic meters

d = 9m

h = ?m

d = 2r

d - diameter

r - radius

r = d/2

r = 9/2

π- 3.142

Insert the values into the formula of volume of cylinder

V = πr^2h

363 = 3.142 * (9/2)^2 * h

363 = 3.142 * 81/4 * h

363 = 63.6255h

Divide both sides by 63.6255 to get the value of h

363/63.6255 = 63.6255h/63.6255

5.705 = h

h = 5.705m

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

Alborosie

Answer:

Water is being pored in the cone with the rate of 401.92 cm³ per second.

Step-by-step explanation:

There is a cone having height h = 10 cm and radius r = 10 cm

That means h = r

Rate of change of water level $\frac{dh}{dt}=2$ cm per second

Since volume of a cone is represented by the formula,

$V=\frac{1}{3}\pi r^{2}h$

Now we have to find the value of $\frac{dV}{dt}$ .

$\frac{dV}{dt}=\frac{d}{dt}(\frac{1}{3}\pi r^{2}h)$

Since r = h

$\frac{dV}{dt}=\frac{d}{dt}(\frac{1}{3}\pi h^{3} )$

$\frac{dV}{dt}=\frac{3}{3}\pi h^{2}.\frac{dh}{dt}$

For h = 8 cm and $\frac{dh}{dt}=2$ cm per second.

$\frac{dV}{dt}=\frac{3}{3}\pi (8)^{2}\times (2)$

$\frac{dV}{dt}=128\pi$ = 401.92 cubic cm per second

Therefore, water is being pored with the rate of 401.92 cm³ per sec.
