Answer:
11
Step-by-step explanation:
f 7? Z = {−21, −14, −7, 0, 7, 14, 21}
First, we need to find the radius from the circle with the area 100pi.
The formula for area of a circle is pi*r^2
pi*r^2= 100pi
We can eliminate the both pi since they are on both sides of the equation. This means r^2=100, and r= the square root of 100, which is 10.
Now we know the radius is 10, we can plug it into the equation for arc sector area- (n is the central angle, replace n with the central angle)
n/360 * 2*pi*r
n/360 * 2*pi*10
n/360 * 20pi
Hope this helps a bit
Answer:
Pretty much f(n)=-3+5n-1
Step-by-step explanation:
for the 50th term 242
Divide the area by the length, which should be 5
