12.  \frac{r-3}{-4-(-8)} =  -5
\frac{r-3}{4} = -5
r - 3 = 4(-5)
r - 3 = -20
r = -20 + 3
r = -17

13.  \frac{r-2}{-2-5} = \frac{5}{6}
\frac{r-2}{-7} =  \frac{5}{6}
6(r - 2) = -7(5)
6r - 12 = -35
6r = -35 + 12
6r = - 23
r = \frac{-23}{6}

Two cylinders are shown below. Which cylinder has the greater volume? Use 3.14 for π. Round to the nearest hundredth. Use the dr
Lemur [1.5K]

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer:

To find which cylinder has the greater volume, we need to find out the volume of each one.

As we all know that the formula used to determine the volume of a cylinder is:

V = The base area*the height

<=> V = πr^{2}h (cubic units)

For example, in my attached photo, we will use this formula to find the volume of each one.

  • 1. Cylinder A:

The base area = πr^{2} = π3.5^{2} = 38.46 square in

The height = 8.5 in

=> the volume of Cylinder A

= The base area*the height

= 38.46*8.5

= 326.91 cubic in

  • 2. Cylinder B:

The base area = πr^{2} = π2.7^{2} = 22.89 square in

The height = 11 in

=> the volume of Cylinder A

= The base area*the height

= 22.89*11

= 251.79  cubic in

Hence, Cylinder B has the greater volume

Mrs. Magee's farm covers 14 1/3 acres. She grows corn on 5/8 of her farm. On how many acres of land does Mrs. Magee grow corn?
Aleonysh [2.5K]
C. 8 23/24. One way you can solve this is by dividing 14 1/3 by 8, because it is the denominator of 5/8, then multiplying the quotient by 5, because it is the numerator of 5/8. (14 1/3 / 8) x 5 = 8 23/24
