Answer:
18.84
Step-by-step explanation:
Diameter = 12
Circumference of a circle = πD
= 3.14* 12
=37.68
Since its a semicircle, (that's half of a circle), divide the result by 2
= 37.68/2
= 18.84
Answer: 12663.3 cubic inches sand is needed for this sandbox.
Step-by-step explanation:
Formula : Volume of cuboid = Base area x height
Volume of sandbox = 1146 x 13 = 14898 cubic inches
Quantity of sand required to fill = 85% of Volume of sandbox
= 0.85 x 14898 [85% = 0.85 ]
= 12663.3 cubic inches
Hence, 12663.3 cubic inches sand is needed for this sandbox.
First, are you really familiar with the graph of y = [x]? If so, your answer choices move that graph up or down.
A. Move the graph of y=[x] UP 3 units
B. Move the graph UP 1 unit
C. Move the graph DOWN 1 unit
D. Move the graph DOWN 3 units
The graph you're given on the problem screen is not a very good one, I think. Would it help to draw y = [x] on a piece of graph paper where one square = 1 unit? The graph you're shown has one square = 2 units, which could lead to some confusion.
So, draw the graph of y = [x], then figure out which way the graph was moved -- and how far -- to get the graph in the problem.

The equation would be Y=-2(x-2)+4
Answer:
39
Step-by-step explanation:
Erica knits 18 squares on Monday. She knits Tuesday through Thursday which is 3 days. She knits 7 squares each day making it 21 total squares these days. For the whole week, she has knitted 18 + 21 = 39.
