Find the perimeter of the figure to the nearest hundredth.
1 answer:
Answer:
28.87 inch
Step-by-step explanation:
The perimeter of a figure is the sum of the length of the boundary sides of the figure surrounding it.
For the above figure the perimeter is the sum of the three sides of the rectangle and circumference of the semicircle.
Diameter of the semicircle forming in the figure is 5 inch(given)
Circumference of the semicircle forming in the figure =
:

Given:
The sequence is 25, 20, 15, 10, 5.
To find:
The ninth term of the given sequence.
Solution:
We have,
25, 20, 15, 10, 5
It is an AP because the difference between two consecutive terms are same.
Here,
First term (a) = 25
Common difference (d) = 20-25
= -5
The nth terms of an AP is
Where, a is the first term and d is the common difference.
Putting a=25, n=9 and d=-5 to get the 9th term.
Therefore, the ninth term of the given sequence is -15.
