Question

rodikova [14]

Answer:

$Volume = 11488.21$

$Area = 2461.76$

Step-by-step explanation:

Given

$Radius, r = 14\ in$

Shape: Sphere

Solving (a): The Volume

This is calculated as:

$Volume = \frac{4}{3}\pi r^3$

Take $\pi$ as 3.14 and substitute 14 for r

$Volume = \frac{4}{3} * 3.14 * 14^3$

$Volume = \frac{4}{3} * 3.14 * 2744$

$Volume = \frac{4 * 3.14 * 2744}{3}$

$Volume = \frac{34464.64}{3}$

$Volume = 11488.21$

Solving (b): The Surface Area

This is calculated as follows:

$Area = 4\pi r^2$

Take $\pi$ as 3.14 and substitute 14 for r

$Area = 4 * 3.14 * 14^2$

$Area = 4 * 3.14 * 196$

$Area = 2461.76$

Which pairs of points would result in a line with a rate of change of 2:1? Select all that apply.

Helen [10]

Answer:

Options A, C, D are true.

Step-by-step explanation:

We have to choose the pair of points from that given in the attached file which will result in a line with a rate of change i.e. slope of 2:1 i.e. 2.

A. The points are (-4,-11) and (-2,-7).

Then the slope of the joining line is $\frac{-7-(-11)}{-2-(-4)} =2$

B. The points are (5,6) and (-5,12).

Then the slope of the joining line is $\frac{12-6}{-5-5} =-\frac{3}{5}$

C. The points are (0,-3) and (-4,-11).

Then the slope of the joining line is $\frac{-11-(-3)}{-4-0} =2$

D. The points are (0,-3) and (5,7).

Then the slope of the joining line is $\frac{7-(-3)}{5-0} =2$

Therefore, options A, C, D are true. (Answer)
