Find the circumference of the circle. Round to the nearest tenth if necessary.
NikAS [45]

Answer:

c.132

Step-by-step explanation:

so we are given the diameter which is 42m **the diameter is the straight line that passes through the middle of the circle**

but in order to find the circumference we need to find the radius **the radius is always half (1/2,0.5) of the diameter**

so we have to divide 42/2 which equals 21

now we need to set up the formula;

c=2πr/c=2xπxr  **when unknown variables such as 'r' are next to another mathematical numeral such as the pi symbol you don't really have to but the multiplication symbol between them**

c=2π21

=131.946891451

and in your case, it seems we must round to the tenths place so the nine then "becomes a ten" and you're left with 132

good luck :)

i hope this helps

have a good one !!

Indicate whether the following statements are True (T) or False (F).
chubhunter [2.5K]
1.  False because a rational is a fraction or part of a number (\frac{3}{2}, 3.2).  \sqrt{49} = 7

2.  True; a real number is any number that isn't imaginary (i, \sqrt{-1})

3.  True; same reason

4.  True; an integer is any number that can be wrote without a fraction or decimal (the opposite of rational).

5.  True; \sqrt{3} \approx 1.32 and that's a decimal.

6.  True;  the natural number system starts from 0 and counts upwards

7.  True;  reason above

SashulF [63]
Hello,
Let's factor:

2(4x-1)² * (x+5) + 6(4x-1)³ * (x+5)
=2(4x-1)²(x+5)*[1+3(4x-1)]
=2(4x-1)²(x+5)(12x-2)
=4(4x-1)²(x+5)(6x-1)
