Answer:

1. c. 628 cubic cm

2. c. 502 cubic inches

Step-by-step explanation:

$V=\pi r^{2} h\\$

1.) 3.14 x 5^2 x 8

3.14 x 25 x 8 = 628

2.) 3.14 x ( 8/2 )^2 x 10

3.14 x 4^2 x 10

3.14 x 16 x 10 = 502.4

<h3>Answer:</h3>

These steps <em>can</em> be used:

combine -6 and 4
combine 15 and -3
multiply 2 by x and -2

<h3>Step-by-step explanation:</h3>

The equation could be solved as follows:

2(x -6 +4) = 15 -3 given

2(x -2) = 15 -3 combine -6 and 4

2(x -2) = 12 combine 15 and -3

2x -4 = 12 multiply 2 by x and -2

2x = 16 add 4 to both sides

x = 8 divide both sides by 2

_____

<em>Alternate solution</em>

At step 4, you could have

x -2 = 6 divide both sides by 2

x = 8 add 2 to both sides

Find the lateral area for the prism

monitta

Lateral area is the area of the sides only.
Each side is a rectangle.
A = 4*8 + 6*8 + (sqrt52) * 8
A = 32 + 48 + 57.7
A = 137.7 ft^2
OR
A = 32 + 48 + 57.69
A = 137.69 ft^2

Depends on required rounding.

A right rectangular prism with square bases has a height of 20 centimeters and a volume of 800 cubic centimeters. Which statemen

slamgirl [31]

Answer:

The diagonal of the base is 4√5 centimeters.

The area of a base is 40 square centimeters.

The area of a lateral side between the bases is about 126.5 square centimeters.

Step-by-step explanation:

The volume of any rectangular prism can be found by the formula

volume =B.h

where B = area of base and h is the height of the prism.

It is given the volume of prism is 800 cubic centimeters and height is 20 centimeters.

Substituting these values in the volume formula :

800= B(20)

Or B= 800÷20=40.

Hence area of base is 40 square centimeters.

The diagonal of base = $\sqrt{80}$ = $4\sqrt{5}$

The Volume of prism is 800 cubic unit and base area is 40 square units .Lateral area = area of all sides except the base = 126.5 square centimeters.
