The radius of a circle is 3.9 in. Find the circumference to the nearest tenth.

masha68 [24]

Answer:

C = 24.5 in

Step-by-step explanation:

Formula to find the circumference of a circle is :

C = 2πr

Here,

r ⇒ radius

So let us solve now.

C = 2πr

C = 2 × π × r

C = 2 × 3.14 × 3.9

C = 24.492 in

So, they've asked for nearest 10th.

Therefore, the answer will be 24.5 in.

Hope this helps you :-)

Let me know if you have any other questions :-)

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).

Mashcka [7]

Multiplying eqn no. two with 4 we add it up with eqn 1.

$4x - 5y = 10 \\ - 4x - 12y = 32 \\$

$- 17y = 42 \\ y = \frac{ - 42}{17}$

When

$- x - 8 = 3y \\ x + 3y = - 8$

$x = - 8 - 3 \frac{ - 42}{17 } \\ x = - 8 + \frac{42}{17} \\ x = \frac{ - 10}{17}$

So, x = - 10/17 and y = - 42/17.

2x3 is 2, then what is the value of x

Svetlanka [38]

2x3 = 2
multiply 2 and 3
6x = 2
divide by 6 on both sides
x = 2/6
simplify
x = 1/3
