Find the volume of the cylinder. Use 3.14 for π.
GarryVolchara [31]

Answer:

50.24ft^3

Step-by-step explanation:

Volume of a cylinder

= Pi r^2 h

Given

pi = 3.14

Radius r = 2 ft and

Height h = 4 ft

Therefore

Volume = 3.14 x 2^2 x 4

= 3.14 x 2 x 2 x 4

= 50.24ft^3

Volunteers for a political campaign gave out 21/38 of their fliers. They gave out the remaining 612 fliers in another neighborho
wel

Answer:

<u>The total number of fliers the volunteers gave out is 1,368: 756 in the first neighborhood and 612 in the second.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Amount of fliers the volunteers gave for a political campaign = 21/38

Remaining 612 were given out in another neighborhood

2. What is the total number of fliers they gave out?

x = Total of fliers

21x/38 = Fliers given out in the first neighborhood

612 = Fliers given out in the second neighborhood

Let's solve for x, this way:

x - 21x/38 = 612

38x - 21x = 612 * 38 (38 is the Lowest Common Denominator)

17x = 23,256

x = 23,256/17

x = 1,368

<u>The total number of fliers the volunteers gave out is 1,368: 756 in the first neighborhood and 612 in the second.</u>

Note: Same answer to question 14676213, answered by me yesterday.

Identify the perimeter of a rectangle in which h=8 ft and A=144x ft2.
WINSTONCH [101]

Answer:

52ft

Step-by-step explanation:

perimeter of a rectangle = 2 (height+ breath)

Area of a rectangle = height× breath

144= 8×L

L= 144/8 = 18ft

perimeter= 2(8+18)

perimeter= 2(26)= 52ft
