Answer:
50.6
Step-by-step explanation:
The perimeter of the circle is 12.56 because we take 1/2 of 8 (the length of the short side of the rectangle) and multiply that by pie (or 3.14). Now that we know that the perimeter of the circle is 12.56 we add that to 8 (short side of the rectangle) and we add that to 15 twice (which is 30)

Answer:
for an infinite geometric series the formula for the sum of the infinite geometric series when the common ratio is less than one is given by
= = 144.
Step-by-step explanation:
i) from the given series we can see that the first term is = 120.
ii) let the common ratio be r.
iii) the second term is 20 = 120 × r
therefore r = 20 ÷ 120 =
iv) the third term is = 20 × r
therefore r = ÷ 20 =
v) for an infinite geometric series the formula for the sum of the infinite geometric series when the common ratio is less than one is given by
= = 144.
