Circumference (rounding)
EleoNora [17]

Answer:

<h2><u>104.9</u></h2>

Step-by-step explanation:

To find the circumference of a circle, we need to use the formula which is

C = 2*π*r

Rewrite with radius

C = 2*π*16.7

Solve

C = 2*π*16.7 = 104.876

Now we have to round. Remember, if it is 4 or below round down and if it is 5 or above, round up.

104.876 - 6 is more than 5

104.88 - 8 is more than 5

<u>104.9 is the final answer</u>

(Picture) MULTIPLYING POLYNOMIALS AND SIMPLIFYING EXPRESSIONS PLEASE HELP!!!!
creativ13 [48]

Answer:

12a^3 +2a^2 +23a+18

Step-by-step explanation:

(3a+2)(4a^2-2a+9)

we multiply 3a+2 inside the parenthesis to find the product

first multiply 3a inside second parenthesis

12a^3 - 6a^2 +27a

now multiply +2 inside second parenthesis

8a^2 - 4a + 18

Now we combine it

12a^3 - 6a^2 +27a+8a^2-4a+18

combine like terms

12a^3 +2a^2 +23a+18

What is the 2010th letter in the following sequence: ABCDEDCBA.
siniylev [52]

Answer:

B

Step-by-step explanation:

The sequence is ABCDEDCBABCDEDCBABCDEDCBA....

⇒The main sequence is the repitition of the sub-sequence ABCDEDCB

2010 when divided by 8 gives a quotient of 251 and a remainder of 2

251×8 = 2008

This means that after the sub-sequence ABCDEDCB is repeated for 251 times, it's last letter B is the 2008^{th} letter of the main sequence

Even after that, the sub-sequence ABCDEDCB keeps repeating and the 2010^{th} letter in the main sequence is the 2^{nd} letter of the sub-sequence ABCDEDCB, that is <u>"B"</u>

the length of a rectangle is 4 times its width. if the perimeter of the rectangle is 100cm, find its length and width
tensa zangetsu [6.8K]

l = 4w

4w + 4w + w + w = 100

w = 10

If the width is 10, then the length has to be 40.

4(10) + 4(10) + 10 + 10 = 100

40 + 40 + 10 + 10 = 100

100 = 100
