Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ = $\sqrt{ab}$ , then

$\sqrt{63}$

= $\sqrt{9(7)}$

= $\sqrt{9}$ × $\sqrt{7}$

= 3 $\sqrt{7}$

A funnel is made up of a partial cone and a cylinder as shown in the figure. The maximum amount of liquid that can be in the fun

zavuch27 [327]

The volume of the partial cone is the volume of the entire funnel minus the volume of the cylindrical part.

The volume of a cylinder is given by:

$V=\pi r^2h$
where: r is the radius of the cylinder and h is the height of the cylinder.

Given that the cylindrical part of the funnel has a height of 1.5 cm and a diameter of 1.5 cm, thus the radius is 1.5 / 2 = 0.75 cm and the volume is given by:

$V=\pi(0.75)^2(1.5)=0.84375\pi=2.65072cm^3$

Therefore, the volume of the partial cone is given by 16.59375 - 2.65072 = 13.94303 cubic cm.

What are misconception may students arise when studying sets of numbers and how to address them?

balandron [24]

Step-by-step explanation:

When studying sets of numbers students have certain misconception

1) the correct of writing the tabular notation form

2) the differentiation between sets ( example certain sets have zero and certain do not have a zero - example 2 all integers are rational numbers but all rational numbers are not integers)

3) types (kinds ) of sets . ( onto - into and binary relation)

4) Domain and Range of sets
