Answer:

Chord 12 cm long subtends an angle of 40 degrees at the center of a circle.

θ= 40° = 0.698 rad

Let R be the radius of circle.

Chord Length = 2Rsin(θ/2)

12=2R sin (0.698 /2)

R= 17.54

Ans: Radius of circle = 17.54 cm

In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 3π/2 radians.

Answer:

Option 4 - $L=9\pi ft.$

Step-by-step explanation:

Given : In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 3π/2 radians.

To find : What is the length of the arc?

Solution :

Length of an arc is given by:

$L=r\theta$

where r is the radius of the circle, r= 6 ft.

and $\theta$ is the angle in radian, $\theta=\frac{3\pi }{2}$

Substitute the value given in the formula,

$L=r\theta$

$L=6\times \frac{3\pi }{2}$

$L=3\times3\pi$

$L=9\pi$

Therefore, Option 4 is correct.

The arc of length is $L=9\pi ft.$

When the coffee is brewed according to directions, a pound of coffee beans yields 50 cups of coffee (4 cups = 1 qt). How many kg

Basile [38]

we know that

$1\ pound=0.453592\ kg$

in this problem

a pound of coffee beans yields $50$ cups of coffee

by proportion

Find the kg of coffee that are required to produce $100$ cups of coffee

$\frac{0.453592}{50}\frac{kg}{cups} =\frac{x}{100}\frac{kg}{cups}\\ \\50*x=100*.453592\\ \\x =0.453592*100/50\\ \\x=0.907184\ kg$

therefore

<u>the answer is</u>

$0.907184\ kg$
