Answer:
forty-five and six tenths
Step-by-step explanation:
45 = forty five
.6 = six tenths
There is no picture, but here are the directions to finding the surface area.
1. Find the area of the square(A = bh) and remember that the base and the height will be the same on a square).
2. Find the area of one of the triangular faces (A = 1/2bh), where the base would also be the length of the side of the square and the height the lateral height of the triangular face).
3. Multiply your answer from 2 by 4 because there are 4 of these.
4. Add you answers for #3 and #1 to get the total surface area.
Break 30 into fifths.
30 broken into 5 pieces gives us 6, yes?
We want 3 of those 6's.
That's 18.
Answer:
14
Step-by-step explanation:
Given:
diameter of circle x = 22 units
diameter of circle y = 16 units
wx = 15 units
Want to find: length of xy
First, I started out by halving the diameters to get to the length of the radii, as that's what was depicted in the problem:
circle x: 22/2 = 11
circle y = 16/2 = 8
Now, you just strategically add..
5 + (11-5) + (8-5)
5 + 6 + 3 = 14 units
The answer is 1/5 or in decimal 0.5
