Answer:
30m
Step-by-step explanation:
A=πr²
225π=πr²
225=r²
r=√225
r=15
d=2r
d=2×15
=30m
I think you mean

basically that measn yo divide that term by the previous term
ok
a3=a1/a2=1/2
a4=a3/a2=(1/2)/2=1/4
a5=a4/a3=(1/4)/(1/2)=1/2
a6=a5/a4=(1/2)/(1/4)=2
a7=a6/a5=2/(1/2)=4
a8=a7/a6=4/2=2
a9=a8/a7=2/4=1/2
a10=a9/a8=(1/2)/2=1/4
ok, so notice a pattern
a3=a9
a4=a10
I therefor conclude that

where w is a whole number
and n>2ok, so
241=6*39+7
so therefor

therefor the 241th term is same as a7 or 4
I say a241 is 4
Answer:
y=-x-2
Step-by-step explanation:
The line passes through the points -2,0 and 0,-2. The line is slanted towards the left so the line has a negative slope.
equation of line with negative slope: y=mx+b
using the rise over run tactic: 2/2= 1
y=-x+b
the y intercept is 0,-2
y=-x-2
