All I can tell you is 12x16=192
As shown in the figures given :
For Figure 1 : perimeter = 8 units [As can be seen in the figure]
For figure 2(with 2 octagons) : perimeter = 8 × 2 - 1 = 15 units [since 1 side is common ]
For figure 2(with 3 octagons) : perimeter = 8 × 3 - 2 = 22 units [since 2 sides is common ]
If one more octagon is added
then perimeter = 8 × 4 - 3 = 29 units [since 3 sides will be common ]
Answer:
Weight of a quarter = 6.25 grams
Weight of a dime = 2.5 grams
Step-by-step explanation:
The weight of a nickel is 80%
The weight of a quarter or the weight of a nickel is 5 grams or weight of a quarter =50.8 = 6.25 grams
Weight of a dime = 50% = 12 (weight of nickel) = 52 = 2.5 grams
Answer:
12.6
Step-by-step explanation:
To find the area of a cylinder, you find the area of the circular base and multiply it by the height. Remember that the area of a circle is pi*r^2. R, the radius, is 2. Putting this into a calculator and rounding to the nearest tenth, you get 12.6. Now that we have the circle, we multiply by the height. Since the height is 1, we have our answer of 12.6.
8 would be the best answer to the question.
