V=(4/3)(pi)(r^3)
V=(4/3)(pi)(8^3)
V=(4/3)(pi)(512)
V=(2048/3)(pi), or around 2144.660585

Answer:

The volume of the sphere is 2144.66 cubic units

Explanation:

The volume of the sphere is given by = \frac{4}{3}\pi r^{3}

Now, we have been given the radius as 8 units. So, putting r=8 in the formula we get,

V= \frac{4}{3}*3.14*8^{3}

= \frac{4*3.1415*512}{3}

= 2144.66 cubic units.

So, the volume of the sphere is 2144.66 cubic units.

Write an absolute value inequality that represents the situation. The area, A, in square inches of a square photo is required to
xz_007 [3.2K]

Answer:

|A - 8.7| < 0.4

Step-by-step explanation:

Given

8.5 < A < 8.9

Required

Write as an absolute value inequality

The absolute value inequality can be derived using

|A - Mid| < Length

First Step: Get the middle of the interval

Mid = \frac{1}{2}(8.5 + 8.9)

Mid = \frac{1}{2}(17.4)

Mid = 8.7

Next: Get the Length of the interval

Length = 8.9 - 8.5

Length = 0.4

Substitute values for Mid and Length in  |A - Mid| < Length

|A - 8.7| < 0.4

Hence:

<em>The absolute inequality is </em>|A - 8.7| < 0.4<em></em>

1. Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 24. How old is each
Andre45 [30]

Answer:

a) Let Kim's age be k, then Kim's sister's age is k/2

k+\frac{k}{2}=24

b) k+\frac{k}{2}=24

1\frac{1}{2}k=24

k=16

\frac{k}{2}=8

Kim's age is 16 while her sister's age is 8.
