Given parameters:
Number of sides of the regular body = 10
A decagon has 10 sides.
Unknown:
Sum of the measures of the interior angles = ?
Solution;
To find the sum of the interior angles of a decagon; use the expression below:
Sum of interior angles = (n - 2) x 180
where;
n = number of sides;
So,
Sum of interior angles = (10 - 2) x 180 = 1440°
The sum of interior angle of a decagon is 1440°
Answer:
3.5 cubic yards of cement we need.
Step-by-step explanation:
Given : You need to order cement to make a concrete sidewalk 3 feet wide and 95 feet long. Assume that the depth of the concrete is 4 inches.
To find : How much cement is needed, in cubic feet? How many cubic yards of cement do you need?
Solution :
The length of the side walk is 95 feet long.
The width of the side walk is 3 feet long.
The depth of the concrete is 4 inches.
Convert inches into feet,
1 inch = 0.083 feet
4 inch =
feet
Volume of the cement required is given by



Converting volume into yards,


Therefore, 3.5 cubic yards of cement we need.
