Answer:
175 cents
Step-by-step explanation:
1 quarter is equal to 25 cents.
Since there are 7 of them,
7 times 25 cents = 175 cents
Lateral surface area of a cylinder: 2πrh, r is the radius, h is the height.
area of the top and bottom circle: πr²
when h=2r, the total surface area is:
2πr(2r)+πr²+πr²=6πr²
the answer is 6πr²
Solution:
we are given that
6 people can sit together at 1 rectangular table.
2 tables are placed together, 10 people can sit together.
14 people can sit if three tables are put together.
It mean we get a sequence
6,10,14..........
So its making an arithmetic progression, where
First term![=a=6](https://tex.z-dn.net/?f=%3Da%3D6)
Common difference![=d=10-6=4](https://tex.z-dn.net/?f=%3Dd%3D10-6%3D4)
Number of terms=number of table![=100](https://tex.z-dn.net/?f=%3D100)
As we know the nth term is given by the formula
![t_n=a+(n-1)d\\ \\ \text{Substitute the values}\\ \\ t_{100}=6+(100-1)\times4\\ \\ t_{100}=6+99 \times4\\ \\ t_{100}=6+396=402\\](https://tex.z-dn.net/?f=t_n%3Da%2B%28n-1%29d%5C%5C%0A%5C%5C%0A%5Ctext%7BSubstitute%20the%20values%7D%5C%5C%0A%5C%5C%0At_%7B100%7D%3D6%2B%28100-1%29%5Ctimes4%5C%5C%0A%5C%5C%0At_%7B100%7D%3D6%2B99%20%5Ctimes4%5C%5C%0A%5C%5C%0At_%7B100%7D%3D6%2B396%3D402%5C%5C)
Hence 402 people can sit.
Area = L*W
Original Area = 12*14 = 168
Multiply the dimensions by 2 = 12*2 = 24 and 14*2 = 28
New Area = 24 *28 = 672
New Area divided by original area = 672/168 = 4
The garden will be 4 times bigger in area
