Answer:

ST = 7.1 in

Step-by-step explanation:

we can use SOH-CAH-TOA because we've got a right triangle

side ST would be 'adjacent'

side TU would be the 'hypotenuse'

so we use Cosine because that's used when you're dealing with adjacent and hypotenuse:

cos 42° = ST/9.5

ST = cos 42° × 9.5

ST = 7.1

What is the exact circumference of the circle?

Delicious77 [7]

For this case, we have that by definition, the circumference of a circle is given by:

$C = \pi * d$

Where:

d: Is the diameter of the circle given by 2r, that is, twice the radius.

If we have a circle with a diameter equal to 8cm, then the circumference is given by:

$C = \pi * 8 \ cm$

ANswer:

Option C

$8 \pi \ cm$
