Answer:
3.14
Step-by-step explanation:
The formula for the area of a circle is 
, where r is the radius. In this circle, the area would therefore be 
. However, since this is only a quarter circle, you need to divide the area by 4, meaning that the area of this shape is 3.14 square units. Hope this helps!
Answer:
common ratio=0.5, a1= 0.08
Step-by-step explanation:
r=a3/a2
r=a4/a3
compare both we get:
a3/a2=a4/a3
subtitute a2=0.04 and a4=1
a3/0.04=1/a3
(a3)^2=0.04*1
(a3)^2=0.04
taking square root in both sides
a3=0.02
For r, r=a3/a2
subtitute a3 and a2 above
r=0.02/0.04
r=0.5 common ratio
For a1
r=a2/a1
0.5=0.04/a1
a1=0.04/0.5
a1=0.08
'Of' in math means 'multiplied by,' so the equation that we can set up is:
So your answer is 320.
Answer:
6
Step-by-step explanation:
replace x with 6 in the ecuation.
4(6)=24 - 8 =16
