Answer: 2.7 radians.

Step-by-step explanation:

The formula we use to find the length of the arc :-

l=\theta r , where \theta is the measure of the central angle  (in radians )and r is the radius .

Given : An arc of length 8 in. is intersected by a central angle in a circle with a radius of 3 in.

i.e. l= 8 in.  and r = 3 in.

From the above formula , we have

8=\theta (3)\\\\\Rightarrrow\ \theta=\dfrac{8}{3}=2.66666666667\approx2.7\text{ radians}  [Rounded to the nearest tenth.]

Hence, the measure of the angle = 2.7 radians.

I have three times as many cats as Alice but Bob has 7 less cats than me. In total we have 56 cats. How many cats do I have?
Nookie1986 [14]

The number of cats that you have is; 27 cats

<h3>How to calculate algebra word problems?</h3>

Let the number of cats alice has be x.

Since you have thrice the amount of cats that alice has, then you have 3x cats.

Bob has 7 less cats than you. Thus, bob has; 3x - 7

If they have a total of 56 cats, then;

x + 3x - 7 + 3x = 56

7x - 7 = 56

7x = 56 + 7

7x = 63

x = 63/7

x = 9

Thus, number of cats you have = 3x = 3 * 9 = 27 cats
