Given that the area of the sector is given by:
A=3.142r² S/360
where:
r is the radius
S is the angle measure of the sector
If Mia solved the equation for S, the equations that she wrote would be found as follows;
From A=3.142r² S/360
making S the subject by first dividing both sides by 3.142r^2 we shall have:
A/3.142r²=S/360
next we multiply both sides by 360
360×A/3.142r²=S/360×360
this will give us
(360A)/(3.142r²)=S
therefore the equation that Mia will get is:
S=(360A)/(3.142r²)
answer:
perimeter- 12 units
area- 4.5 units
step-by-step explanation:
perimeter-
p=4a
=4*3
=12
area-
a=pg/2
=3*3/2
=4.5
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!
If I'm understanding the question right then 10.5^2
Answer:
80,000
Step-by-step explanation:
because you are just adding a extra zero
We know that 
and this is the only point when sin and cos are equal lengths. Because both 
Now if the sin of 30° is a half that would mean that cos of 60° is also a half.
Hope this helps.
