C = 7 and S = 4 hope this helps!
43.96
Explanation:
C=2pi(r)
C=2pi(7)
C=14pi
14 x 3.14 = 43.96
56x² - 49x + 14 = 7(8x² - 7x +2)
_____
The greatest common factor of 56, 49, and 14 is 7.
Step-by-step explanation:
Cubes have square faces, so the area of the base is b².
The volume of the cube is b³.
The height of each pyramid is half the height of the cube, so h = b/2. Which means b = 2h.
The cube is made of 6 square pyramids with the same base and height. Therefore, each pyramid has 1/6 the volume of the cube. So the volume of each pyramid is b³/6.
Answer:
Compare the cost for the each (smallest) unit.
Step-by-step explanation:
You can calculate the cost per unit
For example :
20 ounces of water of brand A cost 1.50
30 ounces of water of brand A cost 2
20 ounces of water cost 1.50/20 = 0.075 dollar per ounce
30 ounces of water cost 2/30 = 0.0677 dollar per ounce
