$Range = 3.169m$

Step-by-step explanation:

Given

See attachment for complete question

Required

Determine the difference between the shortest and the longest

This question implies that we calculate the range.

$Range = Longest - Shortest$

From the table, we have:

$Longest = 8.7m$

$Shortest = 5.531m$

So, we have:

$Range = 8.7m- 5.531m$

$Range = 3.169m$

The volume of a cylinder is 252pi cm^3 and its height is 7 cm

ser-zykov [4K]

Answer:

Step-by-step explanation:

volume= (pi)(radius^2)(h)

252(pi)=(pi)(radius^2)(7)

divide both sides by pi

252=(radius^2)(7)

divide both sides by 7

36=(radius^2)

square root each side
