Answer: The length would be 10 in, and the width would be 5 in.

Step-by-step explanation:

10 is two times greater than 5, and 10 + 10 + 5 + 5 = 30. Therefore, the length of the rectangle would be 10 inches and the width of the rectangle would be 5 inches.

Find the range. 4.7 6.3 5.4 3.2 4.9 3.1 –3.1 9.5 –9.5

WINSTONCH [101]

Answer:

The range is 19

Step-by-step explanation:

First, you have to order the numbers from least to greatest:

-9.5, -3.1, 3.1, 3.2, 4.7, 4.9, 5.4, 6.3, 9.5

Then, you have to find the difference between the largest number and and smallest number. You do this by subtracting them:

9.5 - (-9.5)= 19

So, the range is 19

A cylinder has a radius of 5 and height of 3. what is the volume

Lapatulllka [165]

Answer:

236 cubic units (to 3 significant figures)

Step-by-step explanation:

volume of a cylinder = $\pi$ r²h (where r = radius and h = height)

Therefore, volume = $\pi$ x 5² x 3

= $\pi$ x 25 x 3

= 75 $\pi$

= 236 cubic units (to 3 significant figures)
