Use the arc length formula and the given information to find r.. s = 16 cm, θ = 48°; r = ?
saveliy_v [14]

Answer:

The value for r is 19.1 cm

Step-by-step explanation:

We have been given that  s = 16 cm, θ = 48° and we have to find the radius r.

We know the relation

\theta=\frac{s}{r}\\\\r=\frac{s}{\theta},\text{ where }\theta \text{ is in radian}

Hence, first of all convert the angle in radian

θ = 48°= 0.837758 radian

Therefore, we have

r=\frac{16}{0.837758}\\\\r=19.1\text{ cm}

Tems11 [23]

Answer:

50 legs

Step-by-step explanation:

We know that a dog has 4 legs, a cat has 4 legs, a giraffe has 4 legs, a duck has 2 legs, and a chicken has 2 legs. So, we want to calculate 2(4)+4(4)+1(4)+5(4)+1(2)+3(2), right?

Wrong! It's a trick question! The chickens aren't on the floor, so they don't count. So, we really want 2(4)+4(4)+1(4)+5(4)+1(2).

We multiply it out to get 8+16+4+20+2.

We add these up to get 50.

So, our answer is \boxed{50} legs.
