Ok so area=pir^2
2 circles with same area=2pir^2
circle with 2 times radius=pi(2r)^2=pi4r^2=4pir^2
is 2 circles with same area equal to circle with 2 times radius?
is 2pir^2=4pir^2?
is 2=4?
no
therfor the answer is no
it is because the radius is squaered so the doubled gets doubled makng it quadrupuled when the first one only gets doubled
.6/1.0 = 6/10
3 6/10 or 3 3/5
Answer: 5.6 N/cm^2
============================================
Work Shown:
Pressure = (Force)/(Area)
P = F/A
P = (84 N)/(15 cm^2)
P = (84/15) (N/cm^2)
P = 5.6 N/cm^2
For every square cm, 5.6 newtons of force is applied.
-------------
Extra info:
If you wanted to convert this to pascals, then you would need to convert 15 cm^2 to 0.0015 square meters. Then apply the formula above to get 56,000 pascals. 1 pascal is equivalent to 1 N/m^2.
The teacher ordered the students in 24 ways.
We have given that the total number of students is 4.
4 students are assigned to give presentations.
We have to find the arrangement of the 4 students.
<h3>What is the arrangement?</h3>
An arrangement (or ordering) of a set of objects is called a permutation. (We can also arrange just part of the set of objects.)
In a permutation, the order that we arrange the objects n is important.
4 students can be arranged by 4! ways.

Therefore option 3 is correct.
The teacher ordered the students in 24 ways.
