The radius of a circle is 8 inches. find the number of radians in the central angle of the circle which intercepts an arc of 4 i

Grace [21]

$\sf Hello!$

• $\sf Radius, \:r = 8\: in.$

$\sf Circumference\: of\: the\: circle$ = $\sf 2$ π $\sf r = \sf 2\cdotπ\cdot \sf 8 = \sf 16$ π $\sf in.$
$\sf with\: central\: angle\: of\: 2$ π $\sf radians$

$\sf Then,$

• $\sf Length\: of\: Arc$ = $\sf 4 \:in.$

$\dfrac{\sf 4}{\sf 16π} × \sf 2π$ = $\dfrac{\sf 1}{\sf 2} \: \sf radian$

timurjin [86]

Answer: C

<u>Step-by-step explanation:</u>

Convert each option into scientific notation (Only one digit between 1 and 9 before the decimal point). If you move the decimal place to the left, move the exponent that many units to the right. If you move the decimal place to the right, move the exponent that many units to the left.

$A)\quad 0.176\times 10^{18}\quad =1.76\times 10^{17}\\\text{moved the decimal 1 place to the right and the exponent 1 place to the left}\\\\B)\quad 22.13\times 10^{16}\quad =2.213\times 10^{17}\\\text{moved the decimal 1 place to the left and the exponent 1 place to the right}\\\\C)\quad 31.42\times 10^{16}\quad =3.142\times 10^{17}\\\text{moved the decimal 1 place to the left and the exponent 1 place to the right}$

$D)\quad 125.5\times 10^{15}\quad =1.255\times 10^{17}\\\text{moved the decimal 2 places to the left and the exponent 2 places to the right}$

Since they are all (× 10¹⁷), we can compare the digits:

1.76 2.213 3.142 1.255

The largest one is 3.142 so C is the answer.
