Answer:

The surface area of the cyclinder=2πr²+2πrh

=(2×3.14×10²)+(2×3.14×10×6)

=628.5714285714+377.1428571428

=1005.714285714cm²

round it as possible

Solve the absolute value equation:<br><br> |3x+3|=10

yarga [219]

Answer:

x = 2.33

Step-by-step explanation:

We know that when there is an absolute value sign, the value inside the bars is always positive.

=> I3x + 3I = 10
=> 3x + 3 = 10
=> 3x = 10 - 3
=> 3x = 7
=> x = 7/3
=> x = 2.33 (Rounded to nearest hundredth)

Hence, the value of x is 2.33.

How many ways are there to select 12 countries in the United Nations to serve on a council if 3 are selected from a block of 45,

sattari [20]

Answer: There are 2346953264 ways to do so.

Step-by-step explanation:

Since we have given that

Total number of selected countries = 12

Number of selected countries from a block of 45 = 3

Number of selected countries from a block of 57 = 4

So, remaining number of selected countries from a block of 69.

So, 12-(3+4)=12-7=5

Now, we need to find the number of ways, so we will use "Combination" to select that number of countries.

So, it becomes.

$^{45}C_3\times ^{57}C_4\times ^{57}C_5\\\\=14190\times 395010\times 4187106\\\\=2346953264$

Hence, there are 2346953264 ways to do so.
