I'd say it's "convergent and doesn't have a sum"
because it's multiplying by 3 to get every new number and switching between ± after every new number. there is no sum because it's an infinite series.
Answer:
there are 1250 readers
Step-by-step explanation:
r = readers
4 percent of readers sent letter = 50 recieved letters
r * 4 percent = 50
r * .04 =50
divide by .04 on each side
r = 50/.04
r =1250
Area of the shaded region is 540 – 65.25π.
Solution:
Length of the rectangle = 12 + 9 + 6 + 3 = 30 in
Width of the rectangle = 18 in
Radius of the larger circle (
) = 12 ÷ 2 = 6 in
Radius of the medium circle (
) = 9 ÷ 2 = 4.5 in
Radius of the smaller circle (
) = 6 ÷ 2 = 3 in
Area of the shaded region = Area of the rectangle – Area of the larger circle – Area of the medium circle – Area of the smaller circle




Area of the shaded region is 540 – 65.25π.
