Hello there ! Can I have some help with this question? Thank you !

Luba_88 [7]

Answer:

About 6 hours.

Step-by-step explanation:

The cylinder has a diameter of 10 meters and a depth of 1.4 meters.

First, we can find the volume of the cylinder, given by the formula:

$V=\pi r^2h$

Where r is the radius and h is the height (or depth, in this case).

Since our diameter is 10, our radius is 5.

Therefore, the volume of the cylinder will be (using 3.14 as π):

$V=(3.14)(5)^2(1.4)=109.9\text{ meters} ^3$

Since water is pumped at a rate of 18 cubic meters per hour, it will take then:

$109.9/18=6.10\overline{5}\approx 6\text{ hours}$

So, it will take about 6 hours for the water to completely fill the pool.

17. A hemisphere of lead of radius 7 cm is cast into a right circular cone of height 49 cm. Find

Pavlova-9 [17]

Answer:

$r = 3.74cm$

Step-by-step explanation:

Given

Hemisphere

$Radius = 7cm$

Cone

$Height = 49m$

Required

Determine the radius of the cone

First, we calculate the volume (V1) of the hemisphere.

$V_1 = \frac{2}{3}\pi r^3$

Substitute 7 for r

$V_1 = \frac{2}{3}\pi * 7^3$

$V_1 = \frac{2}{3}\pi * 343$

$V_1 = \frac{686}{3}\pi$

Volume (V2) of a cone is:

$V_2 = \frac{1}{3}\pi r^2h$

Because the lead is cast into a cone, then they have the same volume.

So, we have:

$\frac{686}{3}\pi = \frac{1}{3}\pi r^2h$

$686 = r^2h$

Substitute 49 for h

$686 = r^2 * 49$

Divide both sides by 49

$r^2 = \frac{686}{49}$

$r^2 = 14$

$r = \sqrt{14$

$r = 3.74cm$

Hence, the radius of the cone is 3.74cm
