()) 91 is the quotient of c and 283​
Crazy boy [7]

Hey there,

The word problem is as follows:

  • 91 is the quotient of c and 283

From the word choice you know that this is a division problem therefore in numbers this would become 283 ÷ c = 91.

Now that we know that in order to find c we would have to divide 283 by 91 which is another way to write that equation.

So...

  • 283 ÷ 91 would be 3 \frac{10}{91}

Hope I helped,

FrozenT [24]

Answer:

Radius = 2.90 cm

Step-by-step explanation:

Volume \: of \: Cylinder \:  = \pi {r}^{2} h

220 = 3.14 × {r}^{2} × 8.3

220 = 26.062 × {r}^{2}

220/26.062 = {r}^{2}

{r}^{2} = 8.44 ( approx )

r = √8.44

r = 2.90 cm. (approx)
