Correct answer is 1276.
This an arithmetic series.
Answer:
1) They were multiplied by one power of ten because 2.5x 1^10 is 25, and so that it is easier to divide.
19.625/ 2.5 * 10/10 = 196.25/25
Hope this helps plz hit the crown ;D

Answer:
13. 169π ft²
16. 34π mm
17. 12π in
18. 441π m²
Step-by-step explanation:
Circumference of a circle is calculated as follows:
C = 2π*r
Area of a circle is calculated as follows:
A = π*r²
where <em>r</em> is the radius of the circle
13. circumference of the circle: 26π ft
Then, its radius is:
26π = 2π*r
r = 26π/(2π) = 13 ft
A = π*13² = 169π ft²
16. area of the circle: 289π mm²
Then, its radius is:
289π = π*r²
r = √289
r = 17 mm
C = 2π*17 = 34π mm
17. area of the circle: 113.1 in²
Then, its radius is:
113.1 = π*r²
r = √(113.1/π)
r = 6 in
C = 2π*6 = 12π in
18. circumference of the circle: 131.95 m
Then, its radius is:
131.95 = 2π*r
r = 131.95/(2π)
r = 21 m
A = π*21² = 441π m²
Given:
The first four numbers in a pattern are 4, 2, 1, and 0.5.
To find:
The next three numbers in the pattern.
Solution:
We have a pattern,
4, 2, 1, 0.5
Clearly, it is a GP and the common ratio is because each term is half of its preceding term.
Next term after 0.5 =
Next term after 0.25 =
Next term after 0.125 =
Therefore, the next three numbers in the pattern are 0.25, 0.125 and 0.0625 respectively.
