Cylinders A and B are similar. The volume of cylinder A is 20mm3. Calculate the volume of cylinder B.

MrRa [10]

The question is incomplete. The complete question is :

Cylinders A and B are similar. The length of the cylinder A is 4 mm and the length of cylinder B is 6 mm. The volume of cylinder A is 20mm3. Calculate the volume of cylinder B.

Answer:

67.5 $mm^3$

Step-by-step explanation:

Given that :

Cylinder A and cylinder B are similar.

Let volume of cylinder A = 20 $mm^3$

We know the volume of a cylinder is given by V = $\pi r^2 h$

where, r is the radius of the cylinder

h is the height of the cylinder

We have to find the scale factor.

The length scale factor is = $\frac{6}{4}$

$=\frac{3}{2}$

Area scale factor $=\left(\frac{3}{2}\right)^2$

$=\frac{9}{4}$

∴ Volume scale factor $=\left(\frac{3}{2}\right)^3$

$=\frac{27}{8}$

Therefore, the volume of cylinder B is $=20 \times \frac{27}{8}$

= 67.5 $mm^3$

Kite FGHK is shown. <br> What is the value of m?

Georgia [21]

For this case, the first thing to do is to observe that the figure is symmetrical with respect to the FH axis.

Therefore, the following lengths are the same:

$GH = HK$

So, by equalizing both sides we have:

$5m + 1 = 3m + 7$

From here, we clear the value of m.

We have then:

$5m - 3m = 7 - 1\\2m = 6$

$m = \frac{6}{2}\\m = 3$

Answer:

The value of m is given by:

$m = 3$
