Answer: 905 cu. in.
Step-by-step explanation:
volume = (4/3) * π * r³
= (4/3) * π * 216
Answer:
5
Step-by-step explanation:
3 - 2 = 1
3 + 2 =5
5 x 1 =5
1 inch would equal 2 slices of bread.
So there would be 24 slices in one foot.
multiply 1405 by 24 and you get 33720
so then add 3 to that from the 1 3/4
you know have 33723 1/2 slices of bread. because 3/4-1/2 would be 1/4 which is 1/2 a slice of bread.
so the answer would be 33723 1/2 slices of bread:)
The area of a square is its length times its width: l x w = 361
Since the length of a square is the same as its width, replace 'w' with 'l': l x l = 361
l x l = l² = 361 ---> l = √361 ---> l = √361 ---> l = 19 ft.
Answer:
5 corners : 108 degrees
6 corners : 120 degrees
Step-by-step explanation:
there are (at least) 2 different views to get the result :
officially (usually the teachers' preferred method) you consider a polygon as a combination of non-overlapping triangles. a polygon with n corners or edges we can split into n-2 such triangles.
each triangle has an angle sum of 180 degree.
so, the polygon angle sum is (n-2)×180 degrees.
and each (internal) angle is then (n-2)×180/n
n = 5 : (5-2)×180/5 = 3×36 = 108 degrees
n = 6 : (6-2)×180/6 = 4×30 = 120 degrees
the second approach (I prefer) goes after the external angles of the polygon.
the sum of all external angles in any polygon is 360 degrees (a full circle).
for n corners/edges each external angle is 360/n.
and the internal angle is then the complement to 180 degrees = 180 - 360/n
n = 5 : 180 - 360/5 = 180 - 72 = 108 degrees
n = 6 : 180 - 360/6 = 180 - 60 = 120 degrees
